Motorcycle Battery Charging System Explained 

This is the absolute greatest how to video of any type. You're an excellent teacher. Easy to understand without a lot of useless talking. Great job man.

this is gold, mate! i went from clueless to competent in just a few minutes. thanks man :)

I'm not a mechanic but after watching this video I feel like I understand how these pieces...work which makes it easier to fix...thsnx🏍🏍🏍keep up the good work

The best and simplest explanation on RU-vid. 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

Awesome video, I learned new things today :)

Very informative. Great video

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.

You are great mate... Here in Australia all michanics go around the bush.... You are straight to point. Amazing.

very useful information, thanks

Good video, very well explained.

So good I've watched it twice, I am a motorcycle mechanics student and we went over this subject today I needed to hear it again.

I'm thankful to you. Your 6 year old video made me learn a lot of things about the battery.

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

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.

I already knew everything you said and I have to say you put it into words very nicely. Good job, it sure will help many people to understand this system now better.

Clearly explained like a good teacher. Thank you

Nicely explained. Very basic yet in depth. Thank you for this.

The best explained video ever. Very detailed. Thanks!

This was the best video explaining the charging system! Thank you!

Direct, brief, crytal clear explaination. Cheers from Indonesia

One of the best videos on youtube about motorcycle electric components. Now I know how to check what is wrong with my maxiscoter. Thanks

Wow this is the best explanation of how charging works on a motorcycle.

Wow, nice explanation. Thank you for your time.

Thanks! you explained battery charging well and helped me diagnose my rectifier. Thanks again!!

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.

thank you so much! You explained this very well for me to understand. I'm new to riding motorcycles and this helped me alot. I'm now suscribed to you.

Well Done! Thank you, for that informative explanation. 😊

Thank you for the detailed explanation. You are very helpful.

I'm glad I came across your channel sir... Although I already have some ideas about this topic I found this video of yours very informative because you talk clearly and specifically about your topic... This will be very helpful for people who wants to learn about this topic... Keep on posting more motorcycle related videos... You just earned a subscriber... MORE POWER to you... 😊👍

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

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..

This video just got you another subscriber. Thanks for this video. Very informative.

Thanks for an easy understandable and very informative video!

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.

I wish the technicians knew all this 🙈. Keep up the good work sir

Great video. Really nice and simple explanation. Now I know where to look!

I learnt a lot and subscribed. Thank you.

Thank you. Clear and concise. Great help.

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.

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 :)

amazing explaination , I will trouble shoot my hayabusa battery problem my self now . 😃, all i need is ordered multimeter same like yours on amazon .

Great video. Very professional and informative! Thank you

superb you did a good explanation in detail how does a regular, rotor & a batt works. thanks great guy.👍

Good video... very well explained and articulate👍🏻👌

Thanks bro 👍 i know all these things but your uploading a video of it for those who have no knowledge about this

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.

one of the very best informative video, thanks a lot for such a great info.

Excellently explained. Thank you very much !

Very useful information boss.. just fixed the problem on my Yamaha!

Thanks a lot. That was a super informative video for a beginner like me. Thanks again! Greetings from Stockholm 🇸🇪.

Fantastic video. very helpful and to the point thank you

Nice description and much understanding..

Nice video! Helped a lot

i think this was a good video. Also appreciate that you I was able to understand you clearly. so good job.

Nicely explained Vikas, I'm a fan of your DIY videos.

As always, very good explanation Vikas bro! Thanks :)

hey man you earned a sub from me great video and explanation on everything have a great day!!!

Thank you Vikas. Good information and well delivered to us less knowledgeable guys out here.

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.

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

Excellent vid, very informative..Thanks for sharing ur knowledge and waiting eagerly for ur future videos

Very well explained my brother!

Great explanation and easy to understand 10/10.

6:42-7:03, exactly what I needed to know about checking my battery under a load. Thanks!!

Thanks you sir for teaching so many new ways of takeing bike care and answering are questions in positive manner.

Thanks for the insight. Really appreciate it.

Thank you so much brother. You are have a finest articulation

Thank you for the video. Very informative! 👍🏻

This is very informative video. I got to know about RR unit of a bike. Thanks buddy. keep the good work going......

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.

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

I have a Yamaha grizzly 660 that is over charging, eating the rectifier and then getting the battery over time. It has had several rectifiers and has now had a new stator. It is still over charging and it is being checked for a short somewhere in the wiring but not finding anything. Any thoughts?

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

You have a great way of explaining things you're an awesome teacher thank you so much it was great help to me

Thanks Vikas garu nice info quite useful and very neatly explained.

vVery nice, thanks so much for a very good overview...

great info, very simplified .

Great video and well explained.

Great interpretation, well done. Subscribed!

Beautifully explained. Excellent video. Thank you.

Great explaination...easy to understand..

Thanks for the video! I have a 2014 Duke 200 and have been seeing low battery for a few days now.. Since the battery is changed just an year ago, I went to the nearest mechanic and checked the battery voltage. It goes to slightly above 12V from 11.9ish when the bike is cranked up but doesn't increase when the headlight is ON. Do you think this is something to do with the charging circuit or the battery itself coz it has a lower voltage to start with ?

Great video till today, 2021..... ❤️❤️

very good.. like your explanation

Thanks For the GREAT VIDEO MATE

hey bro I have RX 135 and It runs on 12v 2.5ah battery I installed 12v 18w led projector for headlight will my battery support this setup?

Thanks a ton for this explanation!!

I have a 2013 Aprilia rsv4 bought brand new last year off the show room floor. About a week ago I began having start up problems then it would start just click at the relay I bought a new battery and rectifier. When I tested the charge with the bike running the volt meter numbers jumped around. Could it be a loose ground wire?

Great tutorial. I bought my first motorcycle yesterday

Very nice and comprehensive explanation... Keep up the good work..

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 well done! Greatly appreciated. SUBSCRIBED!

Very well explained video.. I solved my problem. Thanks man.. Bless you!

Nice man.u have done a good job.

very informative video ;) good work.

Very nice and simply explain 👏👏

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....

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 so much for this video... It was my regulator and now I'm getting 13.5 on my bike its charging the battery backup...

Perfect explainations. Thanks
