Can-am Defender charging system test.

Welcome back to the channel. In this video I show you how to check the charging system on this 2018 Can-am Defender HD8. I also show you how to replace the stator. I also have a few links below you can use to find yourself a oil change kit from Can-am. As always if you have any questions about motorcycles, atvs, utvs leave a comment are you can find me on facebook at Limitless Powersports service & repair are you casn email me at [e-mail]

Hi! I have a 2017 Can Am Defender Max HD10 and the battery will not get a charge from the machine, only from a charger. Tested voltage to figure that out and battery was high while not running. I’m wondering why you went straight to the stator and not replace the rectifier first only because it’s much easier to get to. I just replaced my rectifier and it is still not taking a charge from the machine so I’m worried I may have to move on to the stator which looks to be a much tougher job (I’ve never changed my own oil so I’d have to do that AND the stator stuff lol). I just tried to replace the things I could reach and easily replace. If it is NOT the stator that is the issue, what else could be the issue do you think?? Just trying to avoid that part I guess.
I don’t want to pay $150 for a battery if this one is ok (though I just paid $50 for a rectifier for nothing apparently).
PS- is it possible that a lot of mud could cause an issue w the charging system?
Thanks for all your help and your videos!!

So the way a charging system works is the stator & rotor creat AC voltage which is sent to the reg/rec. The job of the reg/rec is to rectify the ac voltage to DC voltage & regulate the amount of voltage being sent to charge the battery.
The reason I always start at the stator & do all the proper testing on it first is because if the stator test good then I know it's going to be a reg/rec problem but I also load test my battery to make sure it is good & also test to see if it is charging & check the battery cables take sure they are tight before I start any of my other test. What I'm going to say might sound rude but it's not meant to be that way. I'm not a parts swapper & hoping I picked the right part to fix my problem. I don't loke to wast my time are my customers $$ on just swapping parts. I have been doong this for about 25 year & i like to find out what caused the failure so in hopes that it doesn’t happen again in the future Also by just replace the reg/rec & not know if the stator is bad can also destroy the new reg/rec if the stator is producing to many ac volts & that can also destroy your battery too. To the best way to start checking your charging system is to start atthe battery & then the stator. If all the test check out good then it will be the reg/rec.
Hope all that makes sense.
Also yes mud can play a big factor in making your charging system go out because the mud with insulate the motor are the reg/rec causing them to over heat & go bad. I hope this helped you out. Feel free to ask me any questions are you can email me.

Just the video I wanted to see except for showing ac voltage phase to phase from stator after repair just as you did prior to repair. What is the correct ac voltage the stator should be putting out phase to phase on the 3 phase stator (1-2, 1-3 & 2-3) at idle and at higher rpm?My son has 2021 Defender XMR with about 120ish hours but it will not keep battery charged. We upgraded to an Odyssey PC1200 agm battery before troubleshooting thinking it needed a battery. The regulator/rectifier is difficult to fully test as far as forward/reverse diode test because it is mosfet style. I have swapped regulator/ rectifier from a friend's Defender with no change. The stator is outputting equal voltage (17 vac idling to 32 vac revved phase to phase) on all 3 phases and is not grounded out though I have only tested for continuity to ground and haven't actually ohmed out. The solution is not clear because the system voltage is higher like it is slightly charging when running. Thanks for any additional info you can provide in addition to your video.

THANK YOU SO MUCH BRO.

No problem. I hope this video helped you out.

@@limitlesspowersportsservic3394 I am getting no increase in ac voltage just like your video showed. Battery hasn’t been charging for past few weeks. Hoping new stator will do the trick!

If I jump started my defender and then unhooked the cables should it stay running even if the battery is very dead
