Aloha, I have a gy6 50 cc moped. And I have a electricial issue. I replaced the battery, the stator, the cdi, and ect. If I leave the bike off for more than 2 days and wen I go start it the battery act like it's dead
Very clear and concise information especially if one is a novice. You should be an full time instructor and not just get grease under your nails. Keep going with your great instructional videos.
omg you saved my life a little with this one. I had watched the video some time ago but just recently picked up a 50 cc buddy. It's missing the front cover - salvage auction. The fargin' rectifier was disconnected! Whether intentional or vibration I don't know but the voltage didn't drop when revving now that's it reconnected. I will be using this to deliver food as an only source of income so it's important. I had to come home yesterday as it got only to the point of kick-starting. You are the best! Now out into that 96 degree weather. lol.
I've been a backyard mechanic for years and considered myself somewhat knowledgeable. Never knew the stator produced AC, and the rectifier converted it to DC. Very helpful video. Thanks for posting.
I just want to say that I’m a new scooter owner which has tons of problems !! This video has single handedly taught me how to diagnose my charging system!! Great video
On my 2011 Suzuki Burgman 650 my battery died. I replaced it and the next day drove around nearly 3hrs made a few stops and turned it on and off several times. Then it wouldn’t start up for me. Had to get a jump start. I set up my multi meter and started to see how much parasitic draw it was having it was bouncing around .24-.28ma. I started unplugging stuff and seeing what had an effect.... nothing until the instrument cluster, I unplugged the cluster and it dropped to .01ma. I’m going to pull the cluster apart and see if anything is damaged.
I replaced the rectifier on my scooter it’s a big one ( rectifier ) and it still won’t recharge but everything thing else works fine ... I also have a buddy 150cc it’s a fast little monkey and it’s stock and it goes 50-52 mph kinda scary since it’s so small it kinda wobbles past 47.mph .. I got a rear flat what the size is the nut to remove rear wheel... oh’ could I put rear tire size 4.00 x 10” instead of the stock 3.50 x 10 “ it rides so low that some times I tap the oil cool thats under the battery compartment when I go up some drive ways ??
Just wanted to say thanks for this video. Helped me trace a faulty seat opening actuator on a Vespa GTS 300 as being the cause of a battery drain that killed the battery on a brand new bike after 1 week! Pulled fuses untik draw dropped from 250ma to 0.004 ma (I wouldn't have known a good reading without this video) then went through the things associated with that fuse. When i pulled the seat actuator it dropped to 0.004ma. Now just need to get it all done under warranty. Thanks for getting us back on the road.

thanks brother , you helped me to understand how to use my voltmeter better too. manuals dont have real good details . fixed my bike doing exactlly what you said , only took 1.5 hrs. no issues..great job !!
Hello Sir I got 50cc sym scooter. Last week while driving the scooter sounds different than normal sounds and in few minute the scooter went off and didn't start. Do you think what could have happened.
Thats tough, it could be a lot of things. But I made a video to try to help you find out why it won't start! ua-cam.com/video/xW5y7a7CB1c/v-deo.html Good luck friend!
Having a starting issue, the bike turns over but does not start. When I kick start it does the same thing. I have a dong fang 50cc scooter. I have replaced the battery, cdi, ignition coil, and spark plug. It just keeps making the same noise.
These are some great tips! I gotta get myself a multi meter! Ever since I had my 49cc scooter upgraded to a 100cc I've been getting all sorts of problems! I recently find myself having to constantly charge my battery every few days, so after watching this video I am convinced that there definitely must be something draining my battery while it's off.
Man that's a weird one. Most of the time a blown fuse is due to a short in the harness. But if the scooter cranks and won't start AND has spark I would try a quick valve clearance check. I made a video to walk you through it ua-cam.com/video/QkkYjRdtQxg/v-deo.html. That is of course unless the scooter has been sitting for a while, in which case I would suspect the carburetor.
Really the only way to get a good charge on the battery is with a battery charger. Riding the scooter will charge the battery up but you may experience a shorter battery life
Please help!!! I have low voltage at the battery, and it drains it. I measured voltage at the stator, like you did in the middle of the video. When its unplugged voltage is good, about 45v (+/-) but when plugged in, it drops to about 4-5v same at the voltage regulator. I get same voltage at the battery, regardless of engine RPM
@@Scooter_911 I have a new rectifier and new stator.. if I unplug rectifier and tone pins, they are all somehow, somewhere connected to ground.. how where could they be connected to ground? Is this even the right way of testing?
I think my brain regulator is faulty as all info is going in my ears but then it gets lost somewhere and I don’t know where, so I guess it’s the regulator
Garret help! besides other problems I had with my Yamaha Zuma 50 (2004) now I've learned that the battery dies super fast even after being charged (dont own a charger myself, took it to my local autoparts store) so the electric start will not work. Example: I had it charged, connected it, horn worked fine. Tried electric start and made that "wah wah" sound you talked about and scooter wouldnt start (it only starts with the kickstart which thanks to you I've learned today that you shouldnt use it everyday) and then right after the horn wouldnt even work, just clicks, test it with my $10 multimeter and it reads less than 10v. How could it die in a matter of minutes or seconds even? I bought that battery on December 2019. Also checked the battery while running and it was about 7 or 9v (not 13 or 14 like you said if the stator is working fine). Hope you read this :( thank you and I love your videos bro you one of the best UA-camrs in my opinion.
Honestly there really is no benefit to a lithium battery in a scooter. And they are more finicky to maintain. Its actually not good for them to be charged by the scooter's charging system like a regular battery.
Big fan! My Kymco 150 has stripped spine threads on the end of crank Shaft! Expensive to fix? Considering 2020 lance classic Cali 200. Good scooter? Reliable brand? Thx
I'll be honest with you I'm not too familiar with the cali 200. I've worked on a lot of cali classic 125s and they were of varying quality. The Lance brand has had its share of lemons like the pch 125 for instance. I dont think they make as good of a product as kymco and genuine (pgo) but a little better than the off brand Chinese stuff.
I did that to my ruckus. Got a new drive face and filed the threads with a small triangle file. The kickstart washer is the only thing engaging the shitty threads but it still works.
Hi.. My bike 400cc Brand new 1 year already change 4 batt coz batt Death.. al ready change Rectrifier , Charging coil. still happen.. they kill the batt.. charging after charge for 8'hour just below 10v..
Thanks for the video. I'm sure it will help someone. Its nice to get some in depth detail I have a suggestion for another episode. How to adjust the idle. And not "Where is the idle screw". I think we all know HOW do adjust it, but where to adjust it is the real problem. How to diagnose it when its too low, and too high, etc.
Wow that is an excellent suggestion! Coincidentally my next planned video will be a carburetor rebuild video. Maybe I will make it a 2 part series and have the second video be "how to properly adjust your carburetor"
I have a Peugeot Speedfight 4 scooter. When the engine is off, a current of 12 mA is drawn from the battery at regular 2-second intervals. Is this a fault? Could this current be drawn by the immobilizer or ECU system? As a result, the battery becomes unable to start the engine after a week of inactivity.
I just bought a 2014 Chinese Kait Model S-08K with only 345 miles. And 10" rim's. The owner told me the starter gear wasn't catching and he ordered a New starter and that he would put it in for me. The owner stated I should kick start the moped until the New One is put in. Well it started by the electric switch. But then I had to ride it while it was lightly raining and the signal's for left and right wasn't working and the horn went from being perfectly sounding to sounding like the horn was drowning in Water. Do these Chinese Moped's have problems when it comes to riding in wet weather? As the Moped I have Now has shown Me it doesn't like Wet weather at all. Is there anything I can do to prevent water getting into important components in front and behind the plastic cover of the Moped? I have a 2012 Kymco Like 50 with over 6,000 Mile's on it. It needs a New exhaust system and New battery. It sounds like a Loud Chainsaw. It has 12" rim's and when I rode it, I could hardly feel the crack's and dip's, but with this light weight Moped from a 250 lb Kymco Like 50 Moped, I am not sure I could ride it during the Winter, Like I did Ride My 2012 Kymco Like 50, the Kymco was Great in the Winter months, but Now I think the 2014 will only be Good when the road's are clear, not Wet with water.
Just replaced my battery and soon taking it in for an oil change. This was a great video and will allow me to have an informed conversation with the guy at the shop. Thanks very much for making this easy to follow and learn! Great tempo and visuals!
Hello. First thank you for the info in the video. I wanted to ask you a question. I have a 2007 honda sh150i and when i measure the battery it reads about 12 to max 13 volts when ideling and 15 to 15.3 when turning the throtle near the max. Is that correct in the high rpm or does it have a bad voltage regulator? Thank you.
Hi, is there a sequence for wires when you connect them from stator to the regulator/rectifier ? Does it matters where any of the 3 yellow cable enter the regulator/rectifier (also yellow) ? A "smart" dude cut the soket . TY !
Excellent question! Actually it does not matter where the stator wires enter the regulator rectifier. All of that voltage all ends up in the same place and leaving as DC on the "voltage out" wire. Throw them back where you please!

Any help on what carby i got so as to try and clean it, fix it and put it back together and hope for the best. Im partially disabled and this will help me do my shopping as a car for short trips is killing me in fuel. Big Cheers From an old fella Downunder🙃(Australia)
Just purchased a 2008 sage green model like you're showing us. Mine charges battery as I ride. As a Tilesetter working with the Schluter Systems Ditra Heat, we test cables with a Megohmeter
The ignition switch on the 170i is very particular and has some small circuit built into the back of it. The regular buddy 125/150 switch bolts right up and plugs in but the bike will not run. Other than that make sure you have good power and connection to the ECM (engine control unit) and check all of your fuses!
Great video! Hope you can help on this issue: A few days ago, while riding my SYM VS 125, a lot of smoke started coming out of the front of the bike and the engine started to fail. I turned off the ignition and cut the battery current. At home I took it apart to see what was going on and the rectifier was visibly burnt. I took the bike to a workshop where they changed the rectifier and the battery, but they didn't solve the problem. The new rectifier continues to heat up a lot and too fast, as if something is short circuiting. As they couldn't solve the problem and it still cost me a few €€, I picked up the motorcycle with the fault. Tests i have done: - the battery is new and has 13.1V before the starter - with the three yellow wires from the stator connected to the rectifier, the bike works fine at low revs, fails at medium and the rectifier heats up uncontrollably; with these wires disconnected from the rectifier, the bike works well at any speed, but as we know, the battery is not charged - at idle the 3 yellow wires measure about 40V from stator - the resistant test on stator show equal values on three wires; no ground conductivity; no open circuit on each coil - apparently all the masses are well connected. Any idea what it could be causing this recurrent failure of the rectifier? Note: traditional G6Y carburetor engine with electronic rectifier and CDI, year 2010.
I know this video is old . But i bought a used scooter this past weekend as a proyect scooter for winter.. charging systen is bad voltage jumps non stop . 8 volts to 15 volts . Non stop . . So i ordered new stator and regulator. Still does the same thing. .. maybe is the flywheel ? Magnet ?
Yamaha 50cc 2013 big voltage drop to 7-8 volts, as soon as I turn ignition on. Before I hit start button. Scooter jump starts ok but I seem to loose voltage as I accelerate. When I turn the ignition off battery goes back to 12.7v
Thanks as this was helpful. If this battery was to be a 100amph 12V battery and the system in question drains the battery very quickly, what sort of rectifier would be used to recharge the battery as quickly as drained. 🤷🏾♂️ Some say rectifiers can't recharge 100 amp batteries and above. Any help?
thank you for your video. A question for you about the battery and the multimeter. I have an old kymco r16 50cc 4t (2009 year) , i think that it's a GY6 motor carburetor system. I've checked the battery with my multimeter and the value is about 12.70.... when i rev up , when i increase the rpm , the multimeter gives me a value about 16.80.... is it too high? Maybe do i have to change the regulator/rectifier? Sometimes i have problems to start my scooter... my battery was off and i recharged it using a charger....
Nice video, thanks. And am happy to see a corner front of my Favorite car , Ford Pinto. I know that everybody blame the Pinto, but my experience was 10 years with no problems, only simple maintenance. And I was avoiding to purchase it from a Friend. Thanks again.
Great.. 12.1V, starter turning over, but not starting nor recharging (this even happens with a fully charged battery). Because of that, it can't be kick-started either. But that's not my only problem. Absolutely no change in voltage, even though my scooter nearly takes off with its stand.. either a wiring connection or rectifier issue. I don't think it's the coils that are to blame in my case.
hi. i change on my 49cc 4T new flywheel, stator, rectifier. obtain 13,3v to 15v but when turn on light voltage drop down even accelerate. please help! thanks
Hi. Great channel with lots of useful tips. Thank you for sharing. The only suggestion so far is to keep the sound effects at a lower volume than your voice. I had to go over some portions a few times to understand what you were saying.
i replaced my stator because it wasn't charging but it's still showing around 2 volts at full throttle and i can't seem to understand why it is doing this
I checked my stator from the main plug. The yellow gave me around 8 vac and the white around 11. Vac and with the engine reved up it will give me about 35 vac. But when I test the wires from the front with the rectifier unplugged it only gives me like .50 volts? Why is that? Please help
My scooter could not keep up with a radio and running light i installed. So did the ac voltage check and either the yellow or white wire i can't remember which one was charging 30ac volts and up when revved and the other one was way lower I think I teens to 20's. So I have ordered 2 more 8 pole stators like the one in it already. They all check out the same. I could not believe they were all bad. I ordered a 11 pole update stator and it has 3 yellow output wires. Upon checking them 2 of them are putting out 30v and up however the 3rd one is low just like the 8 pole stator. This is driving me crazy. Some people say all the wires should put out at least 40 volts and up when revved. Others have said anything over 12volts is good confused.
Hi so I have changed my rectifier. I also changed my my stator. It wasn't brand new it was of my original engine which I know it was working. And it's not likely to have same issue. My battery is draining when engine is on. I did stator test putting red into both connections and black to ground but again was reading 0 on AC this was the issue with both stators. Now I put the black and the red into both connections(not ground obviously but other 2) on the stator wire I get a reading of 40+ volts and 50+ when revving the engine. So am confident it's giving out enough AC to rectifier to change to DC. I have just ordered an wiring harness as this is my next thought on issue. Looking at the earth through my harness and it looks frayed and bubbled in sections..could a bad earth that causes this issue along with maybe other damaged wires that I can not see?? Sorry am not great at explaining. So I hope you understand. Love your content btw, keep it up. You make me want to tackle more and more on my bike.
Hello, i have a Yamaha aerox 50cc and i get 10volts ac out of the stator wire 1 and 18volts out of the stator wire 2.Normally both wires go to the rectifier.When i give trottle it only get a little bit higher...10volts to 12volts and that 18volts to 19-20volts. Is this normal ?
Bought a brand new Tao Tao 150, hooked up the battery and nothing. Checked the battery and it is full. Just not getting power to anything. Turn the key on, no horn, no lights, no power at all. Reconnected it 3x to make sure I had it right??? Help please
My battery keeps showing voltage from 11.5 to 16.8 V when active. The volts change every 30 seconds to anything in that range. Also when fully charged it can still struggle to start but even after a long drive when I stop the engine and start up, it struggles again. I bought a new rectifier and I am having the same issue. Could an exhausted or defect battery be causing my rectifier to keep sending in fluctuating volts as its trying to keep the battery charged?
So I'm getting spark and fuel I adjusted the valves at 14 on the intake and 15 on the exhaust only thing I don't have is the compression tester and I can't get this moped to start I'm ready to pull my hair out 911.. any encouraging thoughts or direction you could give me would be so freaking thankful I appreciate it and I like your shows keep it up I'm learning things though and I appreciate your time.
Are you wearing gloves for safety against electric shock or just trying to keep that grime off your hands? I'm ordering the proper equipment to change my regulator and stator now and just want to make sure I have everything. Thanks for posting, very informational.
I wrecked my bike last year and was almost killed in the accident by a guy rearending me, i bought one of these for $150 just to get me riding again after i recovered and i fucking hate it... runs like crap wont fucking start, battery wont stay charged ext... but for 150... i cant complain, itll kick start to life after a while
When i haven’t used my Yamaha Neos for weeks, because it’s turned winter and it’s to cold to ride my scooter, then the battery dies. Is that normal? I have to charge the battery every single year, when I’m off to go for a ride, when it get’s warmer outside
if anyone can help me. bought a non running 2019 tao tao 49cc scooter. after changing the carb and flushing out the fuel system it was a perfect scoot. the brake light blew, i bought one from amazon, after i replaced it blew everything from the positive side of the battery and the in line fuse was blown. i tried a lot then saw that there was a soldering defect that shorted the low beam. since then i cant charge a battery and every time i rev the engine i blow my headlight. i have replaced the stator and regulator/rectifier . im stumped. anyone who helps gets extra presents from SANTA!!!
Thks four your excellent video I have a Piaggio Zip 2T other day I drive and same one stop me and tell me my rear lights is blinking after 2 days all my lights is blown front and rear I’m surprise my fuse don’t blown also when I drive in full throttle same times is cut don’t the speed what you think is my regulator fault thank you help appreciate
Ok, I am new to this but your videos are helping me to diagnose our scooter. There is power but it won't turn over. It will run for a day and then stop. Did a valve adjustment and it worked then the next morning it wouldn't start. It just will not turn over the engine. Cleaned the carb and air filter, new spark plug and it originally had a crappy way too high voltage additional light on the front which we removed. We figured it was draining the battery. But, put a brand new battery in this morning and it will crank but not turn over. Any suggestions?
Wow! Great in formation , I got a moped from China and no one wanted to touch it . But I follow all your videos . Till I found it was the the batty and my tail light . Thank you for you sharing this video .
I'm having a bit of trouble understanding. I backprobed the regulator/rectifier as described at 6:28 and the voltage barely increased when I revved the engine. I checked for continuity between the ground wire on the regulator/rectifier and the negative terminal on the battery, and there's continuity. Everything else seems to check out. Does this mean my regulator/rectifier is bad? I have a 2009 Kymco Super8 150.
There is a good possibility you do! But when checking the ground side, measure resistance instead of continuity. You want to make sure you have less than 3 ohms resistance and continuity can be deceiving that way. Also make sure your stator output is decent before condemning your regulator rectifier. Good luck!
@@Scooter_911 I'll check again in the morning but if I remember correctly my multimeter said the resistance was less than 1 ohm. Also, the stator wires were giving me 40V AC when I revved. Thanks so much for your help!!
@@Scooter_911 Okay I just checked resistance between the ground wire on the reg/rec and the negative terminal on the battery. With the scooter turned off I get 0.1Ω. When I power it on that jumps to 3.3kΩ. However starting the engine and revving takes it back down to 0Ω. Thanks again for all your help!
What to do if I don't clicking for starting but only groaning noise? What if I'm not getting a reading on my multimeter for the battery it only shows number one (1)? Please help me I can't afford a new bike.

Thank you for doing this video. Your video has more informative than most out there. Keep up the good work man.
Thanks dude! More to come!
GREAT JOB ! YOU FOR SURE NOT WHAT YOU DOING, I learn alot from you now don't know the CHARGE of it but it did help me , thanks Kimm
Thank you so much! And nice pun!
Having a starting issue, the bike turns over but does not start. When I kick start it does the same thing. I have a dong fang 50cc scooter. I have replaced the battery, cdi, ignition coil, and spark plug. It just keeps making the same noise.
Hmmm well check out this video I made to help people diagnose a "no start" ua-cam.com/video/xW5y7a7CB1c/v-deo.html
More of these please
These are some great tips! I gotta get myself a multi meter! Ever since I had my 49cc scooter upgraded to a 100cc I've been getting all sorts of problems! I recently find myself having to constantly charge my battery every few days, so after watching this video I am convinced that there definitely must be something draining my battery while it's off.
Wow! I'm so glad I could shed some light on the subject! Let me know how the diagnosing goes! I'll be here if you have any further questions.
Shit how do i get u to come figure out my kymco agility 50 battery dies every few days pops fuse and wont start. Has spark but wont start
Man that's a weird one. Most of the time a blown fuse is due to a short in the harness. But if the scooter cranks and won't start AND has spark I would try a quick valve clearance check. I made a video to walk you through it ua-cam.com/video/QkkYjRdtQxg/v-deo.html. That is of course unless the scooter has been sitting for a while, in which case I would suspect the carburetor.
i bought new battery for my scooter . is it wrong if i dont charge it first and just connect it ? will it be charged through driving properly?
Really the only way to get a good charge on the battery is with a battery charger. Riding the scooter will charge the battery up but you may experience a shorter battery life
Please i need ur help i got a 1989 250 honda elite scooter i need a fuel pump relay where can i get one quick
Any autoparts store should have one that will work. Just take the old one in and have them match it up!
Please help!!! I have low voltage at the battery, and it drains it. I measured voltage at the stator, like you did in the middle of the video. When its unplugged voltage is good, about 45v (+/-) but when plugged in, it drops to about 4-5v same at the voltage regulator. I get same voltage at the battery, regardless of engine RPM
Sounds like you have a shorted regulator rectifier my friend!
@@Scooter_911 I have a new rectifier and new stator.. if I unplug rectifier and tone pins, they are all somehow, somewhere connected to ground.. how where could they be connected to ground? Is this even the right way of testing?
Ran through everything on my lexomoto turned out it was just a fuse
Nice work!
I think my brain regulator is faulty as all info is going in my ears but then it gets lost somewhere and I don’t know where, so I guess it’s the regulator
This scooter is practically the /exact/ same design and set up as my pgo!
Garret help! besides other problems I had with my Yamaha Zuma 50 (2004) now I've learned that the battery dies super fast even after being charged (dont own a charger myself, took it to my local autoparts store) so the electric start will not work. Example: I had it charged, connected it, horn worked fine. Tried electric start and made that "wah wah" sound you talked about and scooter wouldnt start (it only starts with the kickstart which thanks to you I've learned today that you shouldnt use it everyday) and then right after the horn wouldnt even work, just clicks, test it with my $10 multimeter and it reads less than 10v. How could it die in a matter of minutes or seconds even? I bought that battery on December 2019. Also checked the battery while running and it was about 7 or 9v (not 13 or 14 like you said if the stator is working fine). Hope you read this :( thank you and I love your videos bro you one of the best UA-camrs in my opinion.
Sounds like you might have both a bad battery AND a parasitic drain. Good thing you have that multimeter! You're going to need to use it!
@@Scooter_911 but the battery is practically new man how could this had happened T.T
What do you think about the lithium ion battery for a 150cc please give me your take on this.
Honestly there really is no benefit to a lithium battery in a scooter. And they are more finicky to maintain. Its actually not good for them to be charged by the scooter's charging system like a regular battery.
Awesome video 😶🌫️😶🌫️👌
Big fan! My Kymco 150 has stripped spine threads on the end of crank Shaft! Expensive to fix? Considering 2020 lance classic Cali 200. Good scooter? Reliable brand? Thx
I'll be honest with you I'm not too familiar with the cali 200. I've worked on a lot of cali classic 125s and they were of varying quality. The Lance brand has had its share of lemons like the pch 125 for instance. I dont think they make as good of a product as kymco and genuine (pgo) but a little better than the off brand Chinese stuff.
I did that to my ruckus.
Got a new drive face and filed the threads with a small triangle file.
The kickstart washer is the only thing engaging the shitty threads but it still works.
Awesome as usual, Garrett!!!!!🎉❤
Wish you were in florida, would hire you to fix my bashan bs49q-2
Hi.. My bike 400cc Brand new 1 year already change 4 batt coz batt Death.. al ready change Rectrifier , Charging coil. still happen.. they kill the batt.. charging after charge for 8'hour just below 10v..
Thanks for the video. I'm sure it will help someone. Its nice to get some in depth detail
I have a suggestion for another episode. How to adjust the idle. And not "Where is the idle screw". I think we all know HOW do adjust it, but where to adjust it is the real problem. How to diagnose it when its too low, and too high, etc.
Wow that is an excellent suggestion! Coincidentally my next planned video will be a carburetor rebuild video. Maybe I will make it a 2 part series and have the second video be "how to properly adjust your carburetor"
Thanks for the video! Unplugged the voltage regulator and the ampere dropped! Is replacing the regulator enough to fix the problem?
Yes. Definitely start with replacing the reg/rec and then retest. A shorted stator can cause a lot of issues down stream! Good luck my friend!
@@Scooter_911 🤩
Thank you bro for this video,it help me alot to find diagnosis
Glad to help my friend!
winding is new, rr. is new wiring was tested and still getting 12v. fail could be a low magnet effect?
I haven't seen many magnets go bad. You might have a ground issue or possibly excess resistance in the harness
I have a Peugeot Speedfight 4 scooter. When the engine is off, a current of 12 mA is drawn from the battery at regular 2-second intervals. Is this a fault? Could this current be drawn by the immobilizer or ECU system? As a result, the battery becomes unable to start the engine after a week of inactivity.
doing homework for future project coming up. You get an "A" Thank you very much! will review again.
I just bought a 2014 Chinese Kait Model S-08K with only 345 miles. And 10" rim's. The owner told me the starter gear wasn't catching and he ordered a New starter and that he would put it in for me. The owner stated I should kick start the moped until the New One is put in. Well it started by the electric switch. But then I had to ride it while it was lightly raining and the signal's for left and right wasn't working and the horn went from being perfectly sounding to sounding like the horn was drowning in Water. Do these Chinese Moped's have problems when it comes to riding in wet weather? As the Moped I have Now has shown Me it doesn't like Wet weather at all. Is there anything I can do to prevent water getting into important components in front and behind the plastic cover of the Moped?
I have a 2012 Kymco Like 50 with over 6,000 Mile's on it. It needs a New exhaust system and New battery. It sounds like a Loud Chainsaw. It has 12" rim's and when I rode it, I could hardly feel the crack's and dip's, but with this light weight Moped from a 250 lb Kymco Like 50 Moped, I am not sure I could ride it during the Winter, Like I did Ride My 2012 Kymco Like 50, the Kymco was Great in the Winter months, but Now I think the 2014 will only be Good when the road's are clear, not Wet with water.
Just replaced my battery and soon taking it in for an oil change. This was a great video and will allow me to have an informed conversation with the guy at the shop. Thanks very much for making this easy to follow and learn! Great tempo and visuals!
Mine does like 30-40 volts idle!, and over 100 volt when reved!
Woah
Hello. First thank you for the info in the video. I wanted to ask you a question.
I have a 2007 honda sh150i and when i measure the battery it reads about 12 to max 13 volts when ideling and 15 to 15.3 when turning the throtle near the max. Is that correct in the high rpm or does it have a bad voltage regulator?
Thank you.
Hi, is there a sequence for wires when you connect them from stator to the regulator/rectifier
? Does it matters where any of the 3 yellow cable enter the regulator/rectifier (also yellow) ? A "smart" dude cut the soket . TY !
Excellent question! Actually it does not matter where the stator wires enter the regulator rectifier. All of that voltage all ends up in the same place and leaving as DC on the "voltage out" wire. Throw them back where you please!
@@Scooter_911 Thank you!

Hey I like the way you explain it and I am understanding everything you talk about and thanks for the videos you made I have a 2012 kymco super 8
Just purchased a 2008 sage green model like you're showing us. Mine charges battery as I ride. As a Tilesetter working with the Schluter Systems Ditra Heat, we test cables with a Megohmeter
I have a question I cant seem to find the answer for. I have a 2012 Genuine Buddy 170i. I have no spark and no fuel. What would control both of those?
The ignition switch on the 170i is very particular and has some small circuit built into the back of it. The regular buddy 125/150 switch bolts right up and plugs in but the bike will not run. Other than that make sure you have good power and connection to the ECM (engine control unit) and check all of your fuses!
@@Scooter_911 You saved me a lot of headache. Exactly what it was. Well another 2012 170i back on the road!
@@BrownStripeyCat nice work my friend! Keep it shiny-side up?
You're explanation is very clear, anyone can understand thanks for sharing
Won't electric start
Blinkers, hazard not work. Seat lock fail to work. Horn not work. 09 125cc Buddy kick starts only. Any suggestions here.
Great video!
Hope you can help on this issue:
A few days ago, while riding my SYM VS 125, a lot of smoke started coming out of the front of the bike and the engine started to fail. I turned off the ignition and cut the battery current.
At home I took it apart to see what was going on and the rectifier was visibly burnt.
I took the bike to a workshop where they changed the rectifier and the battery, but they didn't solve the problem. The new rectifier continues to heat up a lot and too fast, as if something is short circuiting.
As they couldn't solve the problem and it still cost me a few €€, I picked up the motorcycle with the fault.
Tests i have done:
- the battery is new and has 13.1V before the starter
- with the three yellow wires from the stator connected to the rectifier, the bike works fine at low revs, fails at medium and the rectifier heats up uncontrollably; with these wires disconnected from the rectifier, the bike works well at any speed, but as we know, the battery is not charged
- at idle the 3 yellow wires measure about 40V from stator
- the resistant test on stator show equal values on three wires; no ground conductivity; no open circuit on each coil
- apparently all the masses are well connected.
Any idea what it could be causing this recurrent failure of the rectifier?
Note: traditional G6Y carburetor engine with electronic rectifier and CDI, year 2010.
I know this video is old . But i bought a used scooter this past weekend as a proyect scooter for winter.. charging systen is bad voltage jumps non stop . 8 volts to 15 volts . Non stop . . So i ordered new stator and regulator. Still does the same thing. .. maybe is the flywheel ? Magnet ?
Literally just finishing fixing my scooter for a 1/10th the price of taking it to the garage thanks to you. You're a star! thanks bro
Yamaha 50cc 2013 big voltage drop to 7-8 volts, as soon as I turn ignition on. Before I hit start button.
Scooter jump starts ok but I seem to loose voltage as I accelerate.
When I turn the ignition off battery goes back to 12.7v
This guy is 2 hott 4 me🔥
Hahaha
Thanks as this was helpful. If this battery was to be a 100amph 12V battery and the system in question drains the battery very quickly, what sort of rectifier would be used to recharge the battery as quickly as drained. 🤷🏾♂️ Some say rectifiers can't recharge 100 amp batteries and above. Any help?
thank you for your video. A question for you about the battery and the multimeter. I have an old kymco r16 50cc 4t (2009 year) , i think that it's a GY6 motor carburetor system. I've checked the battery with my multimeter and the value is about 12.70.... when i rev up , when i increase the rpm , the multimeter gives me a value about 16.80.... is it too high? Maybe do i have to change the regulator/rectifier? Sometimes i have problems to start my scooter... my battery was off and i recharged it using a charger....
My honda elite won't start after about 45mins of being turned off. It rolls over then gets real weak
Sounds like your battery is getting weak my friend!
@@Scooter_911 Wish it were that simple! this is after a new battery. I think vampiric drain or weak starter? ty for your info.
Nice video, thanks. And am happy to see a corner front of my Favorite car , Ford Pinto. I know that everybody blame the Pinto, but my experience was 10 years with no problems, only simple maintenance. And I was avoiding to purchase it from a Friend. Thanks again.
Tom Hardy's new hobby seems to have helped refine his temperament...
Great.. 12.1V, starter turning over, but not starting nor recharging (this even happens with a fully charged battery). Because of that, it can't be kick-started either. But that's not my only problem. Absolutely no change in voltage, even though my scooter nearly takes off with its stand.. either a wiring connection or rectifier issue. I don't think it's the coils that are to blame in my case.
hi. i change on my 49cc 4T new flywheel, stator, rectifier. obtain 13,3v to 15v but when turn on light voltage drop down even accelerate. please help! thanks
Hi. Great channel with lots of useful tips. Thank you for sharing. The only suggestion so far is to keep the sound effects at a lower volume than your voice. I had to go over some portions a few times to understand what you were saying.
i replaced my stator because it wasn't charging but it's still showing around 2 volts at full throttle and i can't seem to understand why it is doing this
Did you check the output voltage with the regulator rectifier disconnected? The problem might have been your regulator rectifier the whole time!
@@Scooter_911 i can't remember but im gonna try that later and see if it shows a different reading
I checked my stator from the main plug. The yellow gave me around 8 vac and the white around 11. Vac and with the engine reved up it will give me about 35 vac. But when I test the wires from the front with the rectifier unplugged it only gives me like .50 volts? Why is that? Please help
My scooter could not keep up with a radio and running light i installed. So did the ac voltage check and either the yellow or white wire i can't remember which one was charging 30ac volts and up when revved and the other one was way lower I think I teens to 20's. So I have ordered 2 more 8 pole stators like the one in it already. They all check out the same. I could not believe they were all bad. I ordered a 11 pole update stator and it has 3 yellow output wires. Upon checking them 2 of them are putting out 30v and up however the 3rd one is low just like the 8 pole stator. This is driving me crazy. Some people say all the wires should put out at least 40 volts and up when revved. Others have said anything over 12volts is good confused.
Hi so I have changed my rectifier. I also changed my my stator. It wasn't brand new it was of my original engine which I know it was working. And it's not likely to have same issue. My battery is draining when engine is on. I did stator test putting red into both connections and black to ground but again was reading 0 on AC this was the issue with both stators. Now I put the black and the red into both connections(not ground obviously but other 2) on the stator wire I get a reading of 40+ volts and 50+ when revving the engine. So am confident it's giving out enough AC to rectifier to change to DC. I have just ordered an wiring harness as this is my next thought on issue. Looking at the earth through my harness and it looks frayed and bubbled in sections..could a bad earth that causes this issue along with maybe other damaged wires that I can not see?? Sorry am not great at explaining. So I hope you understand. Love your content btw, keep it up. You make me want to tackle more and more on my bike.
Hello, i have a Yamaha aerox 50cc and i get 10volts ac out of the stator wire 1 and 18volts out of the stator wire 2.Normally both wires go to the rectifier.When i give trottle it only get a little bit higher...10volts to 12volts and that 18volts to 19-20volts.
Is this normal ?
I have a wolf RX-50 that the marker lights don't work but the high beams, turn signals and brake lights work, what could be my problem?
Bought a brand new Tao Tao 150, hooked up the battery and nothing. Checked the battery and it is full. Just not getting power to anything. Turn the key on, no horn, no lights, no power at all. Reconnected it 3x to make sure I had it right??? Help please
My battery keeps showing voltage from 11.5 to 16.8 V when active. The volts change every 30 seconds to anything in that range. Also when fully charged it can still struggle to start but even after a long drive when I stop the engine and start up, it struggles again.
I bought a new rectifier and I am having the same issue. Could an exhausted or defect battery be causing my rectifier to keep sending in fluctuating volts as its trying to keep the battery charged?
I must jump my battery every time. The new battery was fine for about a week. The scooter will not hold a charge.
So I'm getting spark and fuel I adjusted the valves at 14 on the intake and 15 on the exhaust only thing I don't have is the compression tester and I can't get this moped to start I'm ready to pull my hair out 911.. any encouraging thoughts or direction you could give me would be so freaking thankful I appreciate it and I like your shows keep it up I'm learning things though and I appreciate your time.
Best video on the topic i have ever seen.
@@hansmarheim7620 that is very kind! Thank you very much!
Are you wearing gloves for safety against electric shock or just trying to keep that grime off your hands? I'm ordering the proper equipment to change my regulator and stator now and just want to make sure I have everything. Thanks for posting, very informational.
I wrecked my bike last year and was almost killed in the accident by a guy rearending me, i bought one of these for $150 just to get me riding again after i recovered and i fucking hate it... runs like crap wont fucking start, battery wont stay charged ext... but for 150... i cant complain, itll kick start to life after a while
I got the exact same tool box (box on the left) knew I could trust the video instantly. I wonder what year the box was made ive had it my whole life.
When i haven’t used my Yamaha Neos for weeks, because it’s turned winter and it’s to cold to ride my scooter, then the battery dies. Is that normal? I have to charge the battery every single year, when I’m off to go for a ride, when it get’s warmer outside
if anyone can help me. bought a non running 2019 tao tao 49cc scooter. after changing the carb and flushing out the fuel system it was a perfect scoot. the brake light blew, i bought one from amazon, after i replaced it blew everything from the positive side of the battery and the in line fuse was blown. i tried a lot then saw that there was a soldering defect that shorted the low beam. since then i cant charge a battery and every time i rev the engine i blow my headlight. i have replaced the stator and regulator/rectifier . im stumped. anyone who helps gets extra presents from SANTA!!!
Thks four your excellent video I have a Piaggio Zip 2T other day I drive and same one stop me and tell me my rear lights is blinking after 2 days all my lights is blown front and rear I’m surprise my fuse don’t blown also when I drive in full throttle same times is cut don’t the speed what you think is my regulator fault thank you help appreciate
Ok, I am new to this but your videos are helping me to diagnose our scooter. There is power but it won't turn over. It will run for a day and then stop. Did a valve adjustment and it worked then the next morning it wouldn't start. It just will not turn over the engine. Cleaned the carb and air filter, new spark plug and it originally had a crappy way too high voltage additional light on the front which we removed. We figured it was draining the battery. But, put a brand new battery in this morning and it will crank but not turn over. Any suggestions?
Wow! Great in formation , I got a moped from China and no one wanted to touch it . But I follow all your videos . Till I found it was the the batty and my tail light . Thank you for you sharing this video .
I'm having a bit of trouble understanding. I backprobed the regulator/rectifier as described at 6:28 and the voltage barely increased when I revved the engine. I checked for continuity between the ground wire on the regulator/rectifier and the negative terminal on the battery, and there's continuity. Everything else seems to check out. Does this mean my regulator/rectifier is bad? I have a 2009 Kymco Super8 150.
There is a good possibility you do! But when checking the ground side, measure resistance instead of continuity. You want to make sure you have less than 3 ohms resistance and continuity can be deceiving that way. Also make sure your stator output is decent before condemning your regulator rectifier. Good luck!
@@Scooter_911 I'll check again in the morning but if I remember correctly my multimeter said the resistance was less than 1 ohm. Also, the stator wires were giving me 40V AC when I revved.
Thanks so much for your help!!
@@Muniosi nice work! yep that sounds like you need a reg/rec
@@Scooter_911 Okay I just checked resistance between the ground wire on the reg/rec and the negative terminal on the battery. With the scooter turned off I get 0.1Ω. When I power it on that jumps to 3.3kΩ. However starting the engine and revving takes it back down to 0Ω.
Thanks again for all your help!
Pls dont know whats wrong with my sym fighter 150cc scooter changed d start bt still wunt start
