Easy Fix for No Spark on 150cc Xtreme Moped GY6 Engine
Вставка
- Опубліковано 4 жов 2024
- I tried everything under the moon and found out it was a darn kill switch causing no spark on my junk Chinese 150cc moped scooter.
I'm a noob when it comes to fixing mopeds, this was my first time fixing an electrical system in my life. If I could do it. You can too.
IF THIS DOESNT WORK DO THE FOLLOWING
REPLACE IGNITION COIL, SPARK PLUG, CDI.
IF THAT DOESNT WORK REPLACE STATOR

2 days of chasing wires and diagnosing this and that. I knew it couldn't be this simple. Pulled the wire out of the CDI pigtail, plugged it back in, and fired it up. You're the fucking man.
You got it!
@@BackyardRevivals so with your knowledge, if I get a new CDI, put the wire I disconnected back in the harness, and plug it into the new CDI, SHOULD everything work like normal? Or do I more than likely have another underlying issue?
@@ADEMILY87 if you disconnect your killswitch wire and it runs, this means your killswtich system is stuck grounded which means either your ignition switch, killswitch or kickstand kill switch is bad. New cdi is unlikely to fix it. I would just run a wire from your killswitch wire on ur cdi to a new killswitch, I ended up just buying a lowes light switch for awhile, but eventually upgraded to an Ebay button.
@@BackyardRevivals 👍 You're the man. Thanks again for the video and for responding.
Bought new Battery and CDI put them on still didn't spark waiting for new coil to be delivered and saw this video. Cut the wire and my keeway fact 50 is sparking again. Thanks so much, you're a legend.
Little brother...I just rewired for an 11 pole stator, even made a video about it. 1st 2 rides I was getting intermittent spark, she ran but would shutdown after about 4-5 miles or so. Pulling the spark plug and testing showed nothing. I was thinking it was the carb. mixture until I test the spark plug see I'm no spark. Of course check wiring, CDI, coil, tested everything...Came across your video and this other brother's who both confirmed the same thing. Didn't cut mine, but unseated it from the terminal, and now SPARK! Thank you nephew, I will be making a video in a couple of days and your name WILL be mentioned. Thank again! Oh for anyone else reading this...YES THIS WORKS. SUB #457
Awesome! Glad I could help.
Got done filming 3/4ths of the video...went to kill the bike, of course the kill switch won't work, but turning the ignition won't kill the bike either. How are you killing your engine? I had to unplug the CDI.
@@kachiskid what you do is make a switch from the cut end of the killswitch wire to a ground or the other end of the cut killswitch wire. Alternatively you could also ground out the ignition coil, wire from coil lead to switch than from switch to ground.
The scooter in the video I went with the wire to wire technique and used a push button I ordered from Ebay to complete the killswitch circuit that was cut.
@@BackyardRevivals Okay brother. I'm not going to be able to complete my video, but still will be giving you a shout out and linking your video to one of mine in the near future. I promise you this, if you make a follow-up video to that process you will get a lot of views and subs. No other video like it.
Doesn’t that mean you can’t use the kill switch anymore??
Appreciate that bro, I cut the wire and had spark again, literally saved me so much time and money, I'm going to run it to a toggle switch now and make everything nice and neat, thank you 👍🏼

This video has been copyright claimed by Valvoline and Seafoam. Thanks I will have to try this. I spent half the day trouble troubleshooting my scooter with test lights rewiring and soldering. I spent more time playing with the kill switch than I did installing the engine . Subscribed
Thx for the help man little videos like these make the differences 🔥🔥🔥🔥
For those of you with spark issues, remember to start simple and go from there,,,,CDI,plug, ignition coil,,,these should be the first 3 to look at
Right. I'd say even study the electrical system until you fully understand it. Then it's easy.
@@BackyardRevivals Yea, for sure, but many people are not technical and dont like doing stuff, the CDI is so easy to change along with the coil, and the plug is easy for most, you can solve so much with those 3, then there are some advanced issues,,,,LOL
Same dude just replaced stator cdi ignition coil all spark related wires just to find out it is probably this
You touched on something no one else did
Please consider subscribing, I'm 20 away from 1000!
“And of course, Seafoam”. Love it!!
Thank you, very much, you’re the man! I tried everything! It worked. Thank you thank you thank you!
You got it pal
THIS SAVED ME! thank you for this video!!!!
omg i'd think kill switch would stop starter motor . makes more sense now !!! you can't kick start if kill switch engaged too . this gotta be my issue - new stator,coil, wire ,plug , cdi . thnX in advancE brO !!!
Only this super simple things that works well in my case.... Thank you so much..
You got it G!
Had the same problem years ago. I shorted the kill switch to fix it.
Great work
Thankyou 👍 most CDI have one 4 wire plug but mine has 2 plugs with 5 wires
No problem man, sometimes solving a no spark issue on a chinese scooter can be a lot of steps, but sometimes its something very simple.
Found your video, I have tried almost everything and the last one is the stator. Still waiting for my stator to arrive. I'll give a try with this method. My kill switch previously won't cut the power even I put it on OFF position unless I stop the engine by the ignition key switch. Hope this does the work.
Sounds like it.
@@BackyardRevivals Ok, I've tried this method. Took out the kill switch wire terminal, and start. Still no spark. Must be the stator. Anyway, thanks for the video.
@@YEnbeLLs Dang could also be a random loose wire anywhere. The thing is there is a difference in the killswitch system between AC and DC GY6 scooters. Some have an AC CDI and some have DC CDI. In the video if i remember this is an AC CDI, smaller than the big DC CDI.
@@BackyardRevivals my CDI is AC type. I still believe my CDI works fine. The stator voltage output to CDI is under 10vac when I start. I'll check the wiring later.
I’m going to have to try this. The green wire on my 4pin connector is on the bottom left, not the bottom right (both should be ground though). And my black wire on the 2 pin connector is on the top, not the bottom… gonna switch those around and see what happens
*I bought a new wire harness for my GY6 gokart (slightly different than the mopeds but not a whole lot)
thanks man, worked for me, I've put hours into it, lol
You are the man
Any time.
Thank you finally solved my problem
What was the symptoms you had??? Would it spin over but no spark....i ask cause my kill switch on thr handlebars,when pushed down, the engine will not spin over....like its working? So not sure if this kill switch wire could be my problem...ive already replaced plug, ign coil and stator....all for over $100 & NO luck ..only part left is cdi...and its $140....so not wanting to buy more unnecessary parts.....help!
Just no spark
Dude in the beginning of your vid you touch the black wire with white stripe , that's twisted with together with a green wire that's a ground , I you say "" I don't know what I was doing there"". Well you've got the the coil wire grounded out by having those touching ,,, hope this helps in the future,,Miki
Thanks Miki
thank you
I replaced everything, still no spark. I will try this method as well
Did it work?
@@BackyardRevivals Working witout kill switch wire.
@@s.mungos_00 of course. bad wiring somewhere
God bless brother thank you so much. This worked for me after cleaning the carb. THEN replacing the spark plug. THEN buying a new ignition coil. After 10 plus hours of intense trouble shooting. This ending up bring what worked for me. LOL. I have a wolf jet classic. Must have been the that the kick stand broke and the center kick stand must have been mis signaling.
Correct, easiest fix for the most impossible to find problem.
No Spock, beam down some electrons Scotty!
Computers make excellent and efficient servants, but I have no wish to serve under them
I replaced piston and rings, she started then cut out because carbs was still filling up then I let her idle then she cut out and I checked fire coil in order but no power to fire coil
Thank you so much
U got it, subscribe for more scoot videos to come
Having an issue, mine will just make a click sound at solenoid when trying to start. Also the positive cable gets very warm even after a few tries, tried a new fuse, swapped battery and new solenoid nothing, but it did start with the kick start twice but now it won't kick start anymore either. Ideas? GY6 150cc only 500 miles
Seized motor / seized starter motor?
Will it still cut out on ignition
Is truth I try it and it work 👍
Thanks bro shit really works
You got it!
I really don't understand how this would work I was under the impression that if the motor would turn over than it shouldn't be in the kill switch I didn't think it was that complex
See, the starter can turn over while spark is not happening. Research how to test for spark and you can verify the problem as a spark issue.
Nice video but still didn't solve my no spark issue
Check all da parts
Will a key still turn the bike off? If you snip this wire?
No
Thx it work, but how did you solve the kill switch issue??
Wired in my own, light switch lmao
@@BackyardRevivals to solve the original issue you have to replace the ignition switch?? i have the same problem i replaced the key switch the issue still there..
Its worked thanks for this. But now how to turned off the scooter or how to fix this issue because now it’s starting but can not turned of my scooter
Splice a light switch inline where you cut the killswitch temporarily. Turn off switch to turn on bike, turn on switch to kill bike.
Eventually run two new wires to the key killswitch / stock killswitch.
Hey there ....my scooter is not giving any spark at all....so just to try something u saying If I cut the red wire on the corner of the cdi then I should have spark
The method shown in this video only helps if you're experiencing a killswitch grounding issue. If you have a bad CDI or loose spark plug boot, this will not fix that.
it is possible that i can change my cdi ... with or without battery .. ?
Most models can run without a battery, you can change the cdi with or without battery
My scooter had the same issue. I cut the kill wire on the CDI and finally, a spark. It ran for a few minutes and then refused to start again. Check the spark and no spark again. Going to give the batt. a full charge and try again. No idea why the spark would just quit like that now.
Found its way to a new short maybe? If kill switch isn't connected and live wire has 12v and ignition / timing are hooked up, it'll go.
@@BackyardRevivals so if you have a key and turn it off it will stop the engine and spark?
🤔 I changed everything, still no spark, I'll have to test this out
Stupid kill switch has been bad on every second scooter I've ever bought that was "broken".
I even had one that if the kill switch was connected it would fry the CDI. very strange.
@@BackyardRevivals we need to remove the volcano
@@BackyardRevivals I found out when it fries a CDI, take it off and leave it off, now connect the negative on the battery, leave positive disconnected, open switch on the scooter, touch positive if you see a big spark, it"s the voltage regulator, thanks for posting
@@miketo5828 I just ended up wiring coil to ground with a new kill switch. Switch on, grounds out the coil and kills the spark.
@@BackyardRevivals nice, I learned alot from these things in the last five years... I fix like about 75 per summer now
2 of the four wires going to the ignition switch need to be connected to turn it on they are red and black the other two that you had connected was the kill switch that's why it was always engaged. You don't have to cut that wire going to your cdi. Just put a switch between the green wire and the black/white
Wrong. Look up the wiring diagram, you may not have a GY6 with this type of CDI.
Kick stand is down there’s prob is a kill switch on that!
Ya that might of been what it was, too late now! Lol
How do you turn it off now ? Use the key ?
Have to wire in new killswitch wires or find the problem in the original killswitch wiring.
I did everything you and the rest of the community did too troubleshoot and replace and finally did this and IT WORKED! But my only problem now is that the key won't shut off the bike. Very weird. Any chance you know anything about it?
You have the make a new kill switch. Where you made the cut, you need to splice in a light switch or a button / the original killswitch if it's tests properly ( resistance over wires ) if that doesn't work you can splice into the key ignition system, its the same.
Bad kill switch then, shorting Incompleting circuit. You did aloooot of extra work
Lol that's why I made the video and explained that I did a lot of extra work before figuring out that I had a short somewhere. The killswitch was fine, keyswitch was fine. Must of been the kickstand switch, I wasn't aware of it before I did this video. Wish I still had the scoot id make a few more videos about this subject. Guess I dont need to scooter to make the video.
Norwich New York Screen Repair also my dumb ass realized this was a year old, but ya still helped me out lol, wasn’t kill switch just a new cdi and I had a toasted wire
It didnt work for me should i change the cdi or what man
Worth a shot
What next I've done these things .my question is going t be
Still no spark?
My scooter wont start, when I press brake engine cuts off
If it won't start then how does the engine cut off? Is the wiring modified? Sounds like the brake light is grounding something out? Maybe not enough juice from alternator to create spark and power brake light?
@@BackyardRevivals i start it on kickstarter, but when I brake while driving engine cuts off
@@RedzicAnel I suspect your clutch is broken. When the scooter is off, are you able to roll the scooter easily or does it resist?
@@BackyardRevivals its auotmatic, i dont have a clutch
@@RedzicAnel LOL it's a centrifugal clutch, it's an automatic clutch. Just answer the question.
Did it actually work
Yes
That may have worked for you but cdi,stator,wires first
test them first of course.
So you’re telling me… I just replaced a starter, a stator, a spark plug, AND AN IGNITION COIL, all for a fix that involved snipping one fucking wire?!
That's exactly how it went for me too!
@@BackyardRevivals I shouldn’t of second-guessed myself to be fair, I suspected that it was something to do with the Killswitch from the start.
Oh well I got new parts
@@BackyardRevivals update. Still no spark
@@WowItzAkina look through wiring diagram and check everything
@@WowItzAkina i might make an in depth "understand gy6 spark" video that goes through every case
Wires twisted together on kill switch engaged kill. Wire u snipped grounds out ignition
No the problem happened before the wires were twisted together. IT was for testing
So if i do this will my scooter start? Because now its not starting and I replaced everything
Check ur killswitch. Id make a better video but I dont hsve a gy6 anymore
If we cut the wire to the kill switch, how are we suppose to shut it off?? I want to do this but curious if that first
You have to rewire a new killswitch. I usually just did a push button killswitch.
Use the ignition key. I never use a kill switch. If that switch fails you will realize you never needed it in the first place
hello. so on my cdi in the top right is a yellow and black wire that connects to the spark coil, should i still snip it? if not which wire should i snip
If its a DC cdi it will be double the size of the one in the video and that does not have a killswitch to the cdi. Its always in the same spot. If you are worried just do it far enough from the cdi so that you can always twist the wire back together.
you should also just pop the connector out and instead of sniping yur wires
I just did this and it worked thx man I was going crazy trying to figure it out. The only issue I have now with doing this is when I turn the key off it stayed running. Any suggestions?
Make a switch inbetween the snip so you can re-enable to killswitch or trace your killswitchz and find the bad 1
I will try this. Does anyone know if it actually works?
If your CDI is the kind where the 2 plug has 2 wires not one, then itll work. The reason it works is because that wire provides a ground to the CDI when the killswitch is on / kickstand down / key is not engaged, so when you cut it the bike has no killswitch. You will need to install a manual killswitch or find where the ground is stuck. You could also just cut part of the wire and see if its grounded. If it's not then this will not fix your issue.
Would getting a new Cdi fix it?
@@aaronanderson4907 only if the CDI has gone bad. Does your CDI receive all proper inputs like the trigger signal from the pickup coil?
It is weird if I check the spark by turning the ignition there is not a spark. But if I check it by turning the ignition and flipping the kill switch back and fourth it will inconsistently spark. Also I just replaced the ignition coil
@@aaronanderson4907 sounds like faulty kill switch unplug it
and now how you turn off the scooter ?
Put a lightswitch or a button inline connecting the cut wire. Complete the circuit to shut off the bike. You could also try and find out what is causing the grounding issue, this will require some brain power and a multimeter.
@@BackyardRevivals thanks for reply, I have 120 volts ac going in to the cdi but in the primary coil I have only 20 volts no mater if I change cdi the same result nothing or very weak spark. .. OK thanks anyway.
@@geoepi321975 did you try replacing coil / stator. Parts are cheap enough and spare parts are never a bad thing.
@@BackyardRevivals I replaced stator ,coil, cdi, regulator rectifier, spark plug and ignition switch and problem not solved also I checked all wiring and connections and it's ok maybe it's possessed I don't know what else to do
These scooters are the biggest pile of junk. Owning one is the most frustrating waste of time. If it isn’t one thing, it’s another. I pushed mine more then I ive rode it. No spark this morning. Ran fine when parked, I’m gonna drop it off at the dump.
Noooo just fix it up to a good running point and sell it, buy an already broken one with half the money fix it and it'll last forever
Our gy6 did same thing, never knew if it run or not. Threw bunch part $, nothing, unhooked kill! YES!
Brad Byington kill switch button on handlebar?
@@rjones93257 im assuming the final 1 to CDI.
Norwich New York Screen Repair Its been a while, I replaced the CDI couple years back. I’ll have to look into which wire.
Hello does it matter what cdi you put in ? i have a generic trigger and can i put a gy6 cdi inside ?
If its a gy6 motor you can run a gy6 cdi, if is got the same plugs and it plugs right in then id say try it.
Did you see if it's Ac or DC
Because if you take in the wrong one then you are scooter can be danmed.
ill try this ill let you know. everything is new now lol but my wires have a bad ground so it starts like 1% out of 50 times lol Yes i also purchase starting fluid and did not work, but i will try your method. To me it looks like the stupid cdi freezes the cable wires so by cutting that cable you bypass the frozen motor function to start! great idea ill try that today!
Ya it's amazing what you can do by trial and error lol
Never mind it didn't work
