The best and simplest explanation on UA-cam. Very good. My buddy has a 2001 Honda 750 shadow that has this problem. He took it to a shop they said it was fine and it died the next day with a dead battery. Bought new battery, died the next day. Put in a new stator, died the next day. You narrowed it down and I figured this was it but now I'm certain. Thanks for an excellent video
@@rvkvikas okay I have a1980 s pantera motorcycle and I not sure how makes it do you no how makes the bike and I have a nuthere question I can start it with out the battery how is that it dose have a Kik strat
+danny rose Wow, thank you ! Thank you very much for watching and wish you a fantastic weekend. Hope you are subscribed to the channel and do enjoy my other videos also.
HI Sir, wow very nice video about this issue !!!! Very well explained - And yes, I was facing this problem now several times and now with my Hyosung 650, year 2007. It now happened 3 times that out of the blue the bike is not starting anymore. So I checked the battery with the multimeter and saw its not really charging the battery and stood at 13.5ish volts when I raised the rpm. Now, I disconnected the regulator and checked it with the Multimeter in the way some guys are showing how to do it. I found nothing weird on it, except different numbers (using the diode arrow sign on the meter). So, I am wondering if the regulator really is broken ? - Greetings from Ireland
zcarm Hello My Friend! Sorry for the late reply! I will sure try to help you with regards to the battery charging issue. I would like to send you a detailed text document by email, so that you can do a few checks on your motorbike and let me know your findings.. Do let me know your email ID. Cheers! Have a nice day!
Vikas Rachamalla Hello Vikas, thank you very much for your info. Well, I think I have figured it out already after several tests and it looks like its the rectifier which need to be exchanged....However, I would be happy to get your documentation if you dont mind. I will send you an email with my email ok ? Best regads Berny
I have watched a dozen videos on the explanation of the regulator/rectifier, this is the best one I have seen. You have a way of explaining so that everyone can understand. Thank you for taking the time.
Boss! I tried to learn about battery charging method from other videos, but you come up with the best..You made it so simple to understand..You hit right on the money.. I have pulsar 220, 2011 model..Last time when I went for tour, my bike stopped middle of nowhere, 150 kms away from my home town, It was an electrical malfunction (CDI issue), But with very limited knowledge regarding bike's electrical problem it gave me one hell of a night..So tell me before going for any long tour, which electrical mechanism I should take care about specially my bike does not have any kick start..
hi i got a 2009 Kawasaki zx6r when i ran a test on my yuasa battery i got about 12 .2 volts when i rev the bike to about 5,000 rpms the voltage drops to about 9 volts would that be the stator not generating enough power.
probably not, reg/rec probably failing, look at the three yellow wires going into the plug from the reg/rec, are they going brown, is one going brown/scorched, thats the regulator failing
Its his reg/rec, I ride the zx9r its the same system, the CDI is ignition and nothing to do with charging the battery as you can see from his description of the problem, the bike is running its just using the battery for everything rather than the alternator/stator-reg/rec/to battery.
My bike battery is troubling a lot, gave it to the service centre twice and those idiots couldn't even find the problem. Thanks for the video, now I can tell them about the probable issues.
Awesome Video. I'm having issues with a 1982 Kawasaki KZ440 and it's charging system. I've replaced the Regulator, Stator and battery and after running it for 2 hours I can't get it to start. I've taken the battery back to the store and had it checked after charging it and it tested as good. The Regulator has the correct Ohms. The Stator also tests good on Ohms and is not shorting out. I have not been able to check the voltage output of the stator. I have now moved on to the Starter and the solenoid. Tomorrow I will remove the starter and test it. The Solenoid seem to test good today. I have been able to bump start it but seems like the battery does not get a charge and now seems as if the battery does not have enough amps to turn the motor over. Again tomorrow I will pull the starter and test it to see if it runs out of the bike. Thanks for sharing your knowledge.
Great information. Usually moving pats get detoirated faster. I.e stator due to hot oil circulation & stator coil burns due to poor quality of insulation i.e varnish used in coil wire. Since RR unit doesn't have moving parts their reliability is higher
Best explanation that I have found in days. Really good job! My 2004 Ducati Monster is not charging properly when it is running. When I crank the bike up the voltage drops from 12.6 to 12.3 and than goes up to 12.8 again. I assume 12.8 Volts is not enough to charge it. I will start by replacing the regulator since it is the cheapest part. If that doesn't work I'll move on to the stator.

I have 1 year 3 months old Honda hornet 160r. I have faced this issue yesterday only. I thought the problem is in battery so replaced it with new battery.. But when we checked voltage while bike is running it was not as per the charging logic of bike..Thanks for the knowledge provided with ease now I knw I have to check the bike battery charging system or else m going to get same prob in new battery.. U r best technical moto vlogger I knw in India.. Good work keep it up buddy.. Waiting for your next video

Just the perfect video i was looking for..Thank you so much for the your time creating this video. Your video is truly the most basic of all perfect for just the beginner trying to understand the motorcycle electrical system. cant wait to see more of your motorcycle electrical system repair video.......I have electrical supply problem in my Suzuki Raider 150....always buying a new battery in less than a year usage....Now i know how to troubleshoot them....Hope you have another video specific on checking ac suppy on stator/rotor assembly...Thanks a lot
Such an important part of the bike yet always overlooked. I run a simple USB charger with a digital voltage reader. Always know the status of my charging. After 3 batteries and 2 rectifiers, I now know when the rectifier is on it's way out which is usually the case. Great video.
Great video! Been having some battery issues on my 2014 Ninja 650 where the bike will run fine but after taking a 20min or so break the bike wouldn't crank over again so we end up having to push start it to get it back home. I just replaced my battery after finding out that it had gone bad but now I know about the regulator/rectifier and stator if the new battery doesn't fix the issue. Thanks again for explaining it so simply that even I can manage to understand it lol.
Thanks for a very informative video!I got a Suzuki Boulevard c90. When the motorcycle is running, the bike got enough power to stay running, but if I shut it off, and then try to start it again, the battery is too low to crank the engine. The battery is two weeks old, so it should be good. I short circuit the old battery and wonder if that might have fried the regulator/rectifier... What do you think?
thanks for the explanation. i have a problem with my suzuki gsx 750 es -84 the battery is new but not chargeing, will check everything within your tutorial and see if i can get to the bottom with it. have a nice one :)
Thank you for watching mate. Please do update me on your findings. I would be glad to help you. Hope you enjoy my other videos also. Do subscribe so that you can stay updated with my new videos. Have a good day.
Great video, thank you :) I am a new beginner at the technical stuff and having a problem with the charging system of my Virago, this video was just what I needed for the diagnostic process :)
Brynja Bjorg Gudmundsdottir Thank you very much my friend! Hope you have been able to figure out the problem with the charging system. Please let me know if you need any help. I would be glad to help you. Wish you a good day!
Thanks a lot for the comprehensive video, it helped a lot. Now, as you mentioned during the video about questions, I do have a question if you don't mind. I own a Hyosung Aquila GV250 EFI and my stator was fried a couple of weeks back so my mechanic replaced it with a new one, doing a shitty job, as he removed the supplied plugs and welded the three yellow wires from the stator to the yellow ones of the reg/rec , is it important to know the order of the three (1,2,3) or it does not matter? Anyway, I'm getting 12.8 A on the battery when the engine is off and when running approx. 13.6 - 13.8 A. Should I worry and get a new reg/rec? Thanks in advance
I'm pretty confident after watching your video that the Stator/Rectifier is toast on my bike. Basically the battery isn't charging at low RPS's. The headlight dims. But when you bring the RPM's to 4k and up the headlight brightens up again. Battery is brand new by the way.
Regularly check (yearly) the plug connection to your reg/rec as they tend to melt as the regulator fails and don't just give a dealer your hard earned cash for the exact same model again, look on Ebay for an R1 reg/rec with mosfet connectors and fit that instead, they all do the same job of converting AC to DC and for standard bikes the R1 seems to be fitted with the best from the number 1 makers in japan and thats these guys: Shindengen Electric Manufacturing Co., Ltd.
I have had to replace 3 batteries in the last six months - the same thing happened on all 3 occasions : 1. The engine killed once and two other times, applying pressure on accelerator would make wierd engine noises, 2. The bike once switched off, would not start again, 3. The battery was really hot on all 3 occasions, 4. The battery showed proper voltage but would not charge, 5. All the 2 prior batteries I replaced, would heat every time I rode and on the off occasion, when I rode a little longer than usual with a pillion, point 1 to 3 would repeat, 6. Finally on the third occasion, I changed the regulator rectifier and now the latest battery does not heat at all after riding. I am not sure if my issue is resolved, still can't be confident going on long rides.
This is the video I've been looking for to explain why my battery kept dying. I know believe it is the regulator/rectifier. I will replace it and report back. I have a 150cc scooter, and this vid summed up my problem to a T.
This is a 2005 Yamaha 660 4 wheeler. It checks 18.2 or more at the battery but you put a new rectifier on and it will check 14.2. It will last maybe 4 hours or so of run time but the rectifier is real hot to the touch. It soon gets it and it starts checking 18+ again.
Vikas Rachamalla Bro, that is one good video and i really appreciate your efforts in this direction. One friendly advice though - you can try changing the name of the video to 'Motorcycle Battery Charging Explained' instead of 'Motorcycle battery charging problems?'. That would certainly make it more visible.
Thank you very much Aseem! Your kind words and advice really matters to me. I will change the name right away! Hope you enjoy my other videos also. Do subscribe so that you can stay updated with my new videos. Have a nice day. You can find me on Facebook also.
Hello.. u made me understand whole process crystal n clear..thnx..lemme tell u my issue so m.facing issues like charging voltage is only about 4-5 volts at ideal speed and when i accelerate then it drops to 1-2 volts.. shall i replce this same regulator ,for yamaha szr ... Help 2. How spark plug get starting currnet and how much? Is it approax 600 volt ac??
InTheNameOfJustice Thank you very much mate! Thank you for watching! Hope you enjoy my othervideos also. Do subscribe so that you can stay updated with my new videos. Have a good day.
What do you think could be wrong if the fan drains the battery in slow city traffic? Unless I ride my bike on the highway or at a decent speed my battery will die.
Excelent video dude!, I just found it but I wanted to check if I'd done the correct thing. I had values for 16 v when my bike had started, so I replaced the regulator, but I was guessing if that was the problem. With this video I'm sure. Thks!
Nice video I face this problem in my bike last year, I change my battery and regulator rectifier, After that my bike mechanic Realised ! that problem is with engine is not sending electric city to rectifier, I wasted 5000 rupees for this problem. Past is past leave it, Now i get total idea how motorcycle battery charge automatically thank you for your information see you later
Sorry to hear about your experience. Even I faced serious issues on my Yamaha and no mechanic was able to help with battery charging issues, they only made me buy new parts and I spent huge money with no result. That is when I decided to learn things on my own and I fixed the issue by myself. Thanks again for watching the video. Have a nice day.
Nice bike! Great explanation of how a motorcycle charging system operates! I am considering trying to incorporate a motorcycle charging system into a classic car (1927 Buick) to run some 12V accessories that would draw too much current to just use a 6V to 12V up-converter! So I’m considering trying to add a stator and rectifier inside of the 93 year old factory 6V generator! Again, great explication....
Good day Mr. Rachamalla, please do give me advice with my MC on how to make the charging faster that the discharging cannot overtake it so that I can enjoy my sound system in my MC. Thank you Sir and the summary that you gave is so helpful truly. MC details: - Current Battery: Acid type (Motolite) - Year: 2007 - Make: Honda - Model: Wave 100 - Piston Displacement: 100 - No. of Cylinders: 1 - Fuel: Gas
Hi vikas i also emailed you on the add below. thanks for all the help on the videos. so here goes. i have a 2008 yamaha xt660r. i got it second hand a couple of months ago and i noticed that it has a few ghost issues. Ghost as in, in consistent. not every time but randomly playing up. at first it would cut off randomly while riding at about 30-40kms. i would pull it at the side and start it and would instantly start. it was random. not every time but about2-3 times a week. After reading about the tps issues on the internet i did a diag check and the tps was ok. lately now a new thing has started. while starting the bike on some days when i turn the key you know the funny sound(like a robot ) that the bike makes kind of like a electric motor, well that does not happen and the immobilizer starts blinking with the overheat light on too. the engine is cold and therefore the overheat light makes no sense. also in the odometer it displays a number 51. for this model there is no error 51 in the fault codes. i have checked the cooling system and it works fine. the censor, relays and fuses are ok. i read in another forum that it may be an immobilizer issue. therefore wanted to know how could i check if it was so. the other forum said that if there is an issue with the immobilizer it wont send a signal to the fuel pump. and also forgot to mention that when i try to start the bike with the overheat and immobilizer lights on the motor turns but does not start. then i just leave the bike for sometime and try again and the bike starts normally.
iyron dsilva Hello Iyron, Sorry about the late reply. I was held up during the weekend. The funny sound (like a robot ), it is the sound of the fuel pump initializing, it is important that we hear that sound every time we turn the key. I did some reading about the ERROR code 51, looks like this code is displayed when there is an issue with the Radiator Fan. Either it is not working and some issue with the relay of the fan. You need to check if the fan is functioning well, if the fan is not turning on after the motorbike reaches higher temperatures, it could be an electric issue with the fan or an issue with the thermostat. Now, about the Fuel pump not starting when you turn the key: The immobilizer takes its input from the key, so, you would need to check if there is any dirt in the lock and spray some WD 40 and try again, if it does not work, the KEY could be at fault too, this happened to one of my Cars. Please try and let me know. I will look forward to your reply. You can connect to me on Facebook also. My details are below: facebook.com/vikas.rachamalla facebook.com/Iammotorbiker
And your absolutely right regarding the duke 390 alloy wheels crack,they are designed to perform not to dodge our Indian potholes,no matter whatever bike we ride even if it is a bmw s1000rr hitting a pothole there will definitely be a wheel crack regardless of the whatever highest quality it is.
Thank you very much my friend. Very few people understand this fact.. I got heavy criticism for that video I made.. But, I believed in the fact. Even my Yamaha R1 rear alloy wheel cracked, my friend's Merc AMG wheels cracked (all 4 cracked). So, the issue is with people riding too fast over bad potholes (which is the issue with our roads and us, not the wheels of the Duke 390). Thanks again!
Also some people are so bizarre that they are saying bajaj company produces poor quality bikes If that was true why would companies like KTM and kawasaki partner with them.models like ninja 350 and duke are manufactured at Chakan plant
Great explaining ... Thanks! Do you have the terminal diagram of "which pin connect to where" of a 5 pin rectifier of Honda 125CDI It would be so much appreciated! My firend's 125 wont get a charge at all.. It cranks up but all by alternator power... I checked the red wire from the rectifier to the battery seems not broken and the fuse is ok... Tested with three batteries no charge voltage at all when the engine is running even at high RPMs... Thanks
Re 11:26 I have a 1999 Honda Magna 750. The regulator/rectifier blew up when my brother was riding the bike. I replaced it with a new one, but when I turned the key to the "on" position, the lights didn't turn on. I checked the battery, the stator, the new regulator/rectifier, and the fuses. All are okay, and still, when I turn the key to the "on" position, the lights don’t come on (the kill-switch is not engaged). I don't know what to do next. Any help would be appreciated.
Hi Vikas, great video. I got an 86 xl600r that has a new Ricky stator that works fine. These bikes have separate regulator and rectifer, The one without the cooling fins is getting hot. It seems to be overcharging that it burnt my 3 prone headlight connector and running light in the back.Ive replaced those things but still gets the non cooling finned Part hot , any help is well .appreciated. Thanks Andy Combs
If you are still checking these comments, I would appreciate a reply. 😊 I received a 2006 Yamaha Morphous 250cc Scooter as a gift, but I have been having trouble with the battery. The battery was fairly old and wasn't holding a charge, so I got a new one and replaced it. However, the battery is still running low after riding maybe 10 or 15 miles, even after a full charge. If I turn off the engine after 10 or 15 miles, it won't crank again without a jump. If I keep it running however, it has trouble idling below 1200 RPM. I have to hold the throttle open while sitting at stop lights to keep the engine above 1200 RPM to keep it from stalling. I only have this problem with it idling if it's been running for a few miles and the battery is running low. Otherwise it rides and idles just fine. I am hoping it's just the Rectifier/Regulator and not the Stator itself. Is there any way I can confirm which is the issue? I prefer not to take it into a shop, because they all have several week's wait time because this time of year is very busy. Many thanks in advance. 😊
Hey Vikas just watched it, nicely explained :) My Question :- I have Pulsar 200dtsi Oil Cooled 2009 Model with Amaron BTX5L 5 Ah Dry Battery ( July 2018 ) I often face battery drain problem due to Lockdown. I end up push start, wheel jump at 5th gear later to Garage to charge the Battery. So how many Kilometer or How much time should i ride my bike to maintain the Battery Power. Do I have to ride it Daily, if not than Alternate days or weekly
Great video, I have been researching my battery issue for a week now. After seeing your video, I am confident that I will locate the problem. I am unable to to start my bike. I don't even hear the bike attempting to crank up. I checked the voltage on my Harley 2009 V Rod which read around 5.4. I turned on the lights and the bike immediately dropped down to 2.3. The mechanic said my battery is to low and needs to be charged on a charger. Which leaves me to believe that I may need a new battery. Also, my battery drain due to being exposed to extremely cold weather. Can you please share your thoughts? Thank you in advance. Oh, I just subscribed to your videos.
I am amazed, thank you. In Liverpool, nobody knows about motorcycles! I have always dreamt of owning one. I now have a Kymco ck1 125cc motorbike none starter. I have to ask you, please can you tell me how to charge it? It is off the motorbike, I followed instructions, and managed to remove it, it is housed on the left side, I do not even understand the instructions on the battery charger, it is a noco genius 1. So the rectifier may be not yet the problem. It could be the battery. Please, you talk sense and knowledge. Many thanks

This is good, very easy to understand, I'm now going to check my charging system as my battery is always flat after standing for 2 days
6:42-7:03, exactly what I needed to know about checking my battery under a load. Thanks!!
Thanks for watching. Hope you enjoy my other videos too and hope you subscribe
This was the best video explaining the charging system! Thank you!
+Aaron Agnew Thanks very much mate. Hope you enjoy my other videos too and hope you subscribe
Subscribed! Gonna look through your other video's a bit later. Trying to suss out my charging system problem right now. haha
Such an important part of the bike yet always overlooked. I run a simple USB charger with a digital voltage reader. Always know the status of my charging. After 3 batteries and 2 rectifiers, I now know when the rectifier is on it's way out which is usually the case. Great video.
+Mezzy A Thanks very much. Hope you enjoy my other videos too and hope you subscribe
I wish the technicians knew all this 🙈. Keep up the good work sir
Great video! Been having some battery issues on my 2014 Ninja 650 where the bike will run fine but after taking a 20min or so break the bike wouldn't crank over again so we end up having to push start it to get it back home. I just replaced my battery after finding out that it had gone bad but now I know about the regulator/rectifier and stator if the new battery doesn't fix the issue.
Thanks again for explaining it so simply that even I can manage to understand it lol.
This is the right one, the title and the content tutorial is matchly in inglish, not like other click bait junk
Thanks for a very informative video!I got a Suzuki Boulevard c90. When the motorcycle is running, the bike got enough power to stay running, but if I shut it off, and then try to start it again, the battery is too low to crank the engine. The battery is two weeks old, so it should be good. I short circuit the old battery and wonder if that might have fried the regulator/rectifier... What do you think?
The best explained video ever. Very detailed. Thanks!
Thanks very much mate! Hope you enjoy my other videos too and hope you subscribe..
thanks for the explanation. i have a problem with my suzuki gsx 750 es -84
the battery is new but not chargeing, will check everything within your tutorial and see if i can get to the bottom with it. have a nice one :)
Thank you for watching mate. Please do update me on your findings. I would be glad to help you. Hope you enjoy my other videos also. Do subscribe so that you can stay updated with my new videos. Have a good day.
All I can do is to thank you too for the knowledge
Thank you very much!
Great video, thank you :) I am a new beginner at the technical stuff and having a problem with the charging system of my Virago, this video was just what I needed for the diagnostic process :)
Brynja Bjorg Gudmundsdottir Thank you very much my friend! Hope you have been able to figure out the problem with the charging system. Please let me know if you need any help. I would be glad to help you. Wish you a good day!
Brynja Bjorg Gudmundsdottir Hope you are subscribed to me. Also, hope you enjoy my other videos. Good day!
superb you did a good explanation in detail how does a regular, rotor & a batt works. thanks great guy.👍
Thanks! you explained battery charging well and helped me diagnose my rectifier. Thanks again!!
Thanks a lot for the comprehensive video, it helped a lot.
Now, as you mentioned during the video about questions, I do have a question if you don't mind.
I own a Hyosung Aquila GV250 EFI and my stator was fried a couple of weeks back so my mechanic replaced it with a new one, doing a shitty job, as he removed the supplied plugs and welded the three yellow wires from the stator to the yellow ones of the reg/rec , is it important to know the order of the three (1,2,3) or it does not matter? Anyway, I'm getting 12.8 A on the battery when the engine is off and when running approx. 13.6 - 13.8 A. Should I worry and get a new reg/rec?
Thanks in advance
I'm pretty confident after watching your video that the Stator/Rectifier is toast on my bike. Basically the battery isn't charging at low RPS's. The headlight dims. But when you bring the RPM's to 4k and up the headlight brightens up again. Battery is brand new by the way.
Thanks for watching my video. Hope you enjoy my other videos too and hope you subscribe.
Thanks so much for this video... It was my regulator and now I'm getting 13.5 on my bike its charging the battery backup...
+Swiss Rims Thanks for watching mate. Hope you enjoy my other videos too and hope you subscribe
Regularly check (yearly) the plug connection to your reg/rec as they tend to melt as the regulator fails and don't just give a dealer your hard earned cash for the exact same model again, look on Ebay for an R1 reg/rec with mosfet connectors and fit that instead, they all do the same job of converting AC to DC and for standard bikes the R1 seems to be fitted with the best from the number 1 makers in japan and thats these guys: Shindengen Electric Manufacturing Co., Ltd.
Thank you. Clear and concise. Great help.
I have had to replace 3 batteries in the last six months - the same thing happened on all 3 occasions :
1. The engine killed once and two other times, applying pressure on accelerator would make wierd engine noises, 2. The bike once switched off, would not start again, 3. The battery was really hot on all 3 occasions, 4. The battery showed proper voltage but would not charge, 5. All the 2 prior batteries I replaced, would heat every time I rode and on the off occasion, when I rode a little longer than usual with a pillion, point 1 to 3 would repeat, 6. Finally on the third occasion, I changed the regulator rectifier and now the latest battery does not heat at all after riding.
I am not sure if my issue is resolved, still can't be confident going on long rides.
Very helpful, please tell more about the use of fuses also... thanks
Very useful information boss.. just fixed the problem on my Yamaha!
Thanks Vikas garu nice info quite useful and very neatly explained.
Thank you Vikas. Good information and well delivered to us less knowledgeable guys out here.

Thank you so much brother. You are have a finest articulation
Great video till today, 2021..... ❤️❤️
This is the video I've been looking for to explain why my battery kept dying. I know believe it is the regulator/rectifier. I will replace it and report back. I have a 150cc scooter, and this vid summed up my problem to a T.
+Ezekiel Major Thank you very much for watching! I am glad my video helped :) Hope you are subscribed to my channel and do enjoy my other videos too.
+Vikas Rachamalla (iammotorbiker) Yes, my new regulator/rectifier is on its way. I'll keep u updated.
This is a 2005 Yamaha 660 4 wheeler. It checks 18.2 or more at the battery but you put a new rectifier on and it will check 14.2. It will last maybe 4 hours or so of run time but the rectifier is real hot to the touch. It soon gets it and it starts checking 18+ again.

Hey Can you provide links to multimeter and good external chargers ? Thanks for the video
Vikas Rachamalla Bro, that is one good video and i really appreciate your efforts in this direction. One friendly advice though - you can try changing the name of the video to 'Motorcycle Battery Charging Explained' instead of 'Motorcycle battery charging problems?'. That would certainly make it more visible.
Thank you very much Aseem! Your kind words and advice really matters to me. I will change the name right away! Hope you enjoy my other videos also. Do subscribe so that you can stay updated with my new videos. Have a nice day. You can find me on Facebook also.
Hello.. u made me understand whole process crystal n clear..thnx..lemme tell u my issue so m.facing issues like charging voltage is only about 4-5 volts at ideal speed and when i accelerate then it drops to 1-2 volts.. shall i replce this same regulator ,for yamaha szr ... Help
2. How spark plug get starting currnet and how much? Is it approax 600 volt ac??
Beautifully explained. Excellent video. Thank you.
InTheNameOfJustice Thank you very much mate! Thank you for watching! Hope you enjoy my othervideos also. Do subscribe so that you can stay updated with my new videos. Have a good day.
Vikas Rachamalla I already subbed. Thanks Bro
What do you think could be wrong if the fan drains the battery in slow city traffic? Unless I ride my bike on the highway or at a decent speed my battery will die.
Sir good explanation for battery charging system thanks useful
Excelent video dude!, I just found it but I wanted to check if I'd done the correct thing. I had values for 16 v when my bike had started, so I replaced the regulator, but I was guessing if that was the problem. With this video I'm sure. Thks!
Very nice and simply explain 👏👏
Nice description and much understanding..
Nicely explained Vikas, I'm a fan of your DIY videos.
Thank you very much Amogh! Your comment made my day :)
Nice video
I face this problem in my bike last year, I change my battery and regulator rectifier,
After that my bike mechanic Realised ! that problem is with engine is not sending electric city to rectifier,
I wasted 5000 rupees for this problem.
Past is past leave it, Now i get total idea how motorcycle battery charge automatically thank you for your information see you later
Sorry to hear about your experience. Even I faced serious issues on my Yamaha and no mechanic was able to help with battery charging issues, they only made me buy new parts and I spent huge money with no result. That is when I decided to learn things on my own and I fixed the issue by myself. Thanks again for watching the video. Have a nice day.
As always, very good explanation Vikas bro! Thanks :)
+ஜெயராமன் ஆம்ரவநேஸ்வரன் Thank you very much bro!
You have a great way of explaining things you're an awesome teacher thank you so much it was great help to me
Thanks for watching. Hope you enjoy my other videos too and hope you subscribe.
Nice bike! Great explanation of how a motorcycle charging system operates! I am considering trying to incorporate a motorcycle charging system into a classic car (1927 Buick) to run some 12V accessories that would draw too much current to just use a 6V to 12V up-converter! So I’m considering trying to add a stator and rectifier inside of the 93 year old factory 6V generator!
Again, great explication....
Good day Mr. Rachamalla, please do give me advice with my MC on how to make the charging faster that the discharging cannot overtake it so that I can enjoy my sound system in my MC. Thank you Sir and the summary that you gave is so helpful truly.
MC details:
- Current Battery: Acid type (Motolite)
- Year: 2007
- Make: Honda
- Model: Wave 100
- Piston Displacement: 100
- No. of Cylinders: 1
- Fuel: Gas
Hi vikas i also emailed you on the add below. thanks for all the help on the videos. so here goes.
i have a 2008 yamaha xt660r. i got it second hand a couple of months ago and i noticed that it has a few ghost issues. Ghost as in, in consistent. not every time but randomly playing up. at first it would cut off randomly while riding at about 30-40kms. i would pull it at the side and start it and would instantly start. it was random. not every time but about2-3 times a week. After reading about the tps issues on the internet i did a diag check and the tps was ok.
lately now a new thing has started. while starting the bike on some days when i turn the key you know the funny sound(like a robot ) that the bike makes kind of like a electric motor, well that does not happen and the immobilizer starts blinking with the overheat light on too. the engine is cold and therefore the overheat light makes no sense. also in the odometer it displays a number 51. for this model there is no error 51 in the fault codes. i have checked the cooling system and it works fine. the censor, relays and fuses are ok. i read in another forum that it may be an immobilizer issue. therefore wanted to know how could i check if it was so. the other forum said that if there is an issue with the immobilizer it wont send a signal to the fuel pump. and also forgot to mention that when i try to start the bike with the overheat and immobilizer lights on the motor turns but does not start. then i just leave the bike for sometime and try again and the bike starts normally.
iyron dsilva Hello Iyron,
Sorry about the late reply. I was held up during the weekend. The funny sound (like a robot ), it is the sound of the fuel pump initializing, it is important that we hear that sound every time we turn the key. I did some reading about the ERROR code 51, looks like this code is displayed when there is an issue with the Radiator Fan. Either it is not working and some issue with the relay of the fan. You need to check if the fan is functioning well, if the fan is not turning on after the motorbike reaches higher temperatures, it could be an electric issue with the fan or an issue with the thermostat. Now, about the Fuel pump not starting when you turn the key: The immobilizer takes its input from the key, so, you would need to check if there is any dirt in the lock and spray some WD 40 and try again, if it does not work, the KEY could be at fault too, this happened to one of my Cars. Please try and let me know. I will look forward to your reply. You can connect to me on Facebook also. My details are below:

Great explaination...easy to understand..
Great explanation and easy to understand 10/10.
Hello from newfoundland Canada, my xs 650 no charge to the battery, work on battery only. Was the proplem. Good video ,good man.thanks.
Excellently explained. Thank you very much !
The perfect explanation!

How can I pitch a pin hole in a battery

Great video. Really nice and simple explanation. Now I know where to look!
And your absolutely right regarding the duke 390 alloy wheels crack,they are designed to perform not to dodge our Indian potholes,no matter whatever bike we ride even if it is a bmw s1000rr hitting a pothole there will definitely be a wheel crack regardless of the whatever highest quality it is.
Thank you very much my friend. Very few people understand this fact.. I got heavy criticism for that video I made.. But, I believed in the fact. Even my Yamaha R1 rear alloy wheel cracked, my friend's Merc AMG wheels cracked (all 4 cracked). So, the issue is with people riding too fast over bad potholes (which is the issue with our roads and us, not the wheels of the Duke 390). Thanks again!
Are you on Facebook?
Yeah it's literally insane to hear people saying KTM builds cheap quality parts.
Yes :)
Also some people are so bizarre that they are saying bajaj company produces poor quality bikes If that was true why would companies like KTM and kawasaki partner with them.models like ninja 350 and duke are manufactured at Chakan plant
Great explaining ... Thanks!
Do you have the terminal diagram of "which pin connect to where" of a 5 pin rectifier of Honda 125CDI It would be so much appreciated! My firend's 125 wont get a charge at all.. It cranks up but all by alternator power... I checked the red wire from the rectifier to the battery seems not broken and the fuse is ok... Tested with three batteries no charge voltage at all when the engine is running even at high RPMs...
Thanks
Thanks a lot. That was a super informative video for a beginner like me. Thanks again! Greetings from Stockholm 🇸🇪.
+Gabriel Alares Thanks very much mate. Hope you enjoy my other videos too and hope you subscribe.
Watching in 2021 still helpful
Re 11:26
I have a 1999 Honda Magna 750. The regulator/rectifier blew up when my brother was riding the bike. I replaced it with a new one, but when I turned the key to the "on" position, the lights didn't turn on. I checked the battery, the stator, the new regulator/rectifier, and the fuses. All are okay, and still, when I turn the key to the "on" position, the lights don’t come on (the kill-switch is not engaged).
I don't know what to do next. Any help would be appreciated.
Perfect explainations. Thanks
+Va Le Thanks mate! Hope you are subscribed and do enjoy my other videos too..

Hi Vikas, great video. I got an 86 xl600r that has a new Ricky stator that works fine. These bikes have separate regulator and rectifer, The one without the cooling fins is getting hot. It seems to be overcharging that it burnt my 3 prone headlight connector and running light in the back.Ive replaced those things but still gets the non cooling finned Part hot , any help is well .appreciated. Thanks Andy Combs
If you are still checking these comments, I would appreciate a reply. 😊
I received a 2006 Yamaha Morphous 250cc Scooter as a gift, but I have been having trouble with the battery. The battery was fairly old and wasn't holding a charge, so I got a new one and replaced it.
However, the battery is still running low after riding maybe 10 or 15 miles, even after a full charge. If I turn off the engine after 10 or 15 miles, it won't crank again without a jump. If I keep it running however, it has trouble idling below 1200 RPM. I have to hold the throttle open while sitting at stop lights to keep the engine above 1200 RPM to keep it from stalling. I only have this problem with it idling if it's been running for a few miles and the battery is running low. Otherwise it rides and idles just fine. I am hoping it's just the Rectifier/Regulator and not the Stator itself. Is there any way I can confirm which is the issue?
I prefer not to take it into a shop, because they all have several week's wait time because this time of year is very busy.
Many thanks in advance. 😊
This is very informative video. I got to know about RR unit of a bike. Thanks buddy. keep the good work going......
Hey Vikas just watched it, nicely explained :)
My Question :-
I have Pulsar 200dtsi Oil Cooled 2009 Model with Amaron BTX5L 5 Ah Dry Battery ( July 2018 )
I often face battery drain problem due to Lockdown.
I end up push start, wheel jump at 5th gear later to Garage to charge the Battery.
So how many Kilometer or How much time should i ride my bike to maintain the Battery Power.
Do I have to ride it Daily, if not than Alternate days or weekly
Great video, I have been researching my battery issue for a week now. After seeing your video, I am confident that I will locate the problem.
I am unable to to start my bike. I don't even hear the bike attempting to crank up. I checked the voltage on my Harley 2009 V Rod which read around 5.4. I turned on the lights and the bike immediately dropped down to 2.3. The mechanic said my battery is to low and needs to be charged on a charger. Which leaves me to believe that I may need a new battery. Also, my battery drain due to being exposed to extremely cold weather.
Can you please share your thoughts? Thank you in advance.
Oh, I just subscribed to your videos.
I am amazed, thank you. In Liverpool, nobody knows about motorcycles! I have always dreamt of owning one. I now have a Kymco ck1 125cc motorbike none starter. I have to ask you, please can you tell me how to charge it? It is off the motorbike, I followed instructions, and managed to remove it, it is housed on the left side, I do not even understand the instructions on the battery charger, it is a noco genius 1. So the rectifier may be not yet the problem. It could be the battery. Please, you talk sense and knowledge. Many thanks
i think this was a good video. Also appreciate that you I was able to understand you clearly. so good job.
very good knowledgable videos
