How to Check Your Motorcycle Charging System 

When you were unraveling those multimeter wires, I felt that on a personal level lmao

Great video you keep it simple and clear. Thank you very much!

very helpful, ty for the demo

Thank you Cody,a great understanding of finding out if a charging system is healthy, Excellent knowledge & tricks Friend,take Care 🙂🙂🙂

Hi Cody, just a quick note on analog systems without benefit of modern diagnostic equipment. A little over a year ago I was having problems with charging system on my 2000 V Star 1100. Without going into it deeply, lets just say that my battery kept dying, the Regulator/Rectifier kept burning out and once even started a fire. My initial knee kick response was to change the stator which I did. Being short on cash I was forced to get one on ebay which I now see was a total mistake, but you live and learn. To continue, after the third RR failed, I came to the conclusion that my problem was the stator and so got one from a local motorcycle salvage yard out of a running motorcycle. This solved the issue and has never returned. All this after spending major coin on a local dealership shop who in the end could only suggest a wire harness change. They had been working with me and despite my suggestions to thoroughly check the stator they could only come up with the harness change. My misgivings about this action were supported by the fact that the problem continued, a burned out RR and a dead battery. It was then that I took stock of what had conspired and the results then decided to change the stator again, this proved to be the answer. I mention all this just to illustrate how reasoning and deduction can win the day in ANY trouble shooting scenario.

Good quality video. Thanks Cody!

Thanks Awesome Video !!Hopefully This will Help Me Diagnose My Softail Duece!!

good one well explained

great video! extremely informational. great explanations. been DIY mechanic for a few years now.

Thanks dude, great intro into something I didn't understand that well.

Thank you Cody that was super helpful

Great info! I just put a new Yuasa Ytz10s in Yamaha XSR900. How often should i charge it with my battery tender jr. and for how long each charge? Thanks

Thanx help a lot

hi ...can you please tell me how a motorcycle with two source of electricity (battery and Stator) work together without any Short-circuit in the wire harness and other components !!

😮😮 Sabre V65!! thanks for sharing

where is the stator located in the vex left/right/front crank case?

Hi, MD great videos keep em comin. I m restoring an 80' Suzuki GS 850 GL, have replaced reg/rect. (new), CDI box (used), Stator (new), Accel coils & wires (new), New plugs . New battery. It starts quick and runs great, BUT for only 4 to 5 minutes max,then it will start lightly popin' (backfiring) CDI gets very hot and finally engine dies.IF I throttle it hard will struggle to run a bit longer but CDI will start smoking I fried the previous CDI that way. IF I come back after about 30 mins. It will start and will run for another 4-5 mins CDI gets blazing hot and dies. Help!

Hi I have a 94 vf750 magna the stator wires the three yellow ones two of them were ripped out or in half by the chain does it matter which one goes where?would really appreciate any feedback you may have

Thanks Bro,nice video and now I can do the same,cool.

Can I run a Mr Gasket 42s on my 06 Honda Shadow 1100 Spirit?

So bottom line, even at full RPM voltage should not increase beyond 14.2?

Good evening, first time is 12.52, Running- light on bright staying at 12.12 - 12.14,

Hi! gdevening, How do I check if the water in the radiator is circulating. (just to be more confident that my water pump is working well) more power and thank you

Awesome Cody - I'd buy you a beer or two if you were in northern Louisiana

Bro! I'm having no spark probs with my v star 650, 2002. Not sure how I can get ahold of you or Vise versa. I like and can understand the way u break things down. Man I need help! I'm about to lose my job because if this.... Look me up face book, google I dont know how without putting personal info out there

Love your channel dude. One of the best DIY MC channels out there. Keep it up!

How can I do this if the bike isn't currently running? (still needs the carb installed, but I'm looking for electrical issues right now because the turn signals and headlight don't work.)

Ahhh I love you my man love you

Can i tap the volt meter at lamp?

Hi I am having a serious problem with my 2014 Yamaha R6 and I believe it's totally electrical basically the rectifier harness is totally burnt and shout out. Now I tried to rewire it myself and I was actually going to hardwire it to the rectifier but I just ordered a new rectifier and a new harness so I'm going to take it to the mechanic this week and get that done get the stator put in and get that electrical situation figured out. Now my question to you is number one the wires were all messed up and they were shorted out my 40 boss solenoid fuse and I knew right away that that's what that was because the buyers were all out and a total mess. I rode the bike a little bit today with the rectifier on hooked and didn't have any problem with the bike starting up or Anythink and I know that's not a good thing to do but the battery is brand new and I keep the battery on the battery tender every and I know that's not a good thing to do but the battery is brand new and I keep the battery on the battery tender every and I know that's not a good thing to do but the battery is brand new and I keep the battery on the battery tender every month I and I know that's not a good thing to do but the battery is brand new and I keep the battery on the battery tender everyday and also have a three month warranty on this battery so if it goes I can get a new one. Now my first question to you is what would make that rectifier harness burn out like that is that the sign of a bad stator? And my second question is I have a 2004 Yamaha YZF R6 and the stator wire doesn't directly go into the rectifier there seems to be some type of wire or relay harness that is 5 wires that plugs into the rectifier so if the 2004 Yamaha R6 stator wire is only 3 plug and play and that plugs into another three where do the five wires come from. and when I bought this new stator I also bought a new rectifier with the new harness what y'all be having a professional put on for me. please if you can get back to me ASAP so I know what's going on with my bike thank you so much I love you videos and cheers from Philadelphia Brian

Mine is 12.6 with bike off and about 12.4 at idle. At about 3-4k rpm goes higher, 13.15 volt max. I’m assuming all is good but don’t understand why my battery went on full charge with the Battery Tender after a ride. I’m wandering if these old 80’s Hondas can’t produce much charge unless cruising at higher rpm

HI,Nice bit of explaining cheers, if you rev the engine and the meter stayed at 13 something volts not 14 plus does that mean that the regulator is dead, cheers DAVE

Some older bikes run the lights straight off AC volts my bike was charging 13.8 volts but then started breaking down with the lights on had already replaced the regulater/rectifier so i ordered a new stator to try next

I have a 97 Honda shadow spirit 1100 (vt 1100). I’ve owned for 9 years and I’ve replaced approx 8 batteries. Recently I started to investigate as to the reason I’m replacing so many batteries. I checked the open voltage many times and the result are the same. Battery output cold engine off 12.6-13 volts. Start bike and it jumps to around 13.8-13.9 at idle. Clymer Manual indicates 13.9-14.9 is normal voltage output to the battery. When RPMs are increased voltage drops to 13.4-13.5 volts. I replaced the rectifier/ regulator and stator and the results are exactly the same. Any suggestions?

I have a digital volt meter on my Harley so i can always tell what my volts are

Hi Cody now I have found you ! I have the brains however is there a Multimeter make that I can purchase That will will test STATORS (MULTI STAGE ) DIODS /RECTIFIERS / A/C AND D/C AND Include an OSCILLOSCOPE !! cheers BRIAN !! 😢i

Im having a charging and starting problem on a 85 honda elite 250 i have to hook a battery booster on to start themat idle its showing 12.4 but then when i rev it the voltage drop to about 6 to 7 volts at the battery

Hi and thanks very much for the video! I went through this process myself, and everything went similarly (12.40ish at rest, up to 13.80ish running) EXCEPT when revved the bike, my voltage actually DECREASED. I tried a few times, same thing. Any idea why it might do this? 2004 VTX 1300 Thanks!

What if it's reading 14v at idle and 14v at 5k rpm?

I accidentally hooked up my battery backwards and fixed it immediately. Did I do damage to the Charging system?? charging system question Laura?

In addition my bike is a honda steed vlx 400. again thank you. . ..

Hi! My yamaha R3 got charging problem when i ride it in hot weather or traffic. But going strong in night or cool weather. It got some burn in rectifier plug also. What would you recommend me to do?

@5k mine still at 12.78 ?

Any advice would be much appreciated

Back tire was moving need to adjust that clutch!!

Hey man, just changed my stator cuz my bike killed two batteries, I have tested the regulator rectifier it seemed to work fine, after changing the stator the idle voltage is 13 but when I put rpm on it drops to 12.5, my battery died after 16miles of riding in 2 days, what do you suggest me to do? Can't take it to the shop cuz they charge me lots of money and I'm broke (my bike is a 2002 yamaha vstar 1100)

thaaaaanks

My bike with RPM i see voltage going down What happen?

what might it mean when when I increase RPM the voltage drops down to about 12.5V, at idle it's 13.9V?

What if you're only getting around 13.5 at higher rpms? Is this a bad regulator/rectifier?

My battery is chargerd at 12.8 when bike is on its 11.8 and doesn't change when revd is it my rectifier or my stator?

I want to know most how to use multimeter

My gs500 has a drainage issue :( I’m a new rider

I had a car that when it was only charging on the battery. I had a voltmeter in the cigarette lighter and it began flashing when below 11.7v. was able to catch it in time before the car left me stranded and changed out the alternator. Yesterday the battery ran completely flat on my Yamaha Bolt and took 8 hours for roadside service to come and $250 to get towed home. Want to make sure it's actually the battery because a new one worked fine.

2:45 to skip ahead

This should have been a 3 minute video. 4 at the most. As the old tv series Dragnet used to say. "Just the facts".

I am gonna sound stupid but better to ask a dumb question than do something dumb to my bike. Question. Where is the rectifier on a 1987 1100 shadow?

Don't no about u I just have two hands myself

Didin't help at all

dont play with your saliva like that dude it's terrible.
