Posted 03 October 2020 - 01:13 PM

I just picked up a 16 Summit X 800 pull start with 1800 miles. I got it with a known P1563 code (high voltage on system voltage circuit), but the sled starts and runs fine. Brought it home and noticed the capacitor starting to smoke, super hot to the touch. The stator and capacitor are supposed to be new. Any ides on what to do or check for next? I'm guessing the capacitor is fried at this point, hopefully not an ecm? I'm not an electrical guy so any help would be greatly appreciated! Thanks in advance!!

Got the capacitor removed. Appears to be leaking from somewhere, which might explain why it was sizzling earlier. Also, are these dents normal? And would it be smart to just replace this with a new one or would it likely get burnt up also? Thanks again!20201003_141106.jpg 20201003_141127.jpg

Correct, any leaking or swelling of a capacitor indicates it's done.
I'm pretty sure I had that same code last winter, sled would run but had gauge problems and I couldn't get any rpm out of it. Stator was done, I can't remember but either one winding was shorted to another, or one was an open circuit.
Capacitor failures aren't common, so that fact that both were just replaced might indicate a wiring short somewhere, or that the guy replaced both because of a misdiagnosis, or maybe preventative maintenance. Or maybe you were lied to.
In any case I'd still check out my wiring, specifically for shorts to ground or other circuits

If you are having over voltage on the 55 volt circuit, test the stator for proper resistance and cranking output. This will tell you if the stator is good or not. If the stator tests ok, you could certainly have a bad capacitor.  
 

A short downstream of the stator will normally cause a low voltage. A grounded stator or damaged flywheel can cause a high voltage output.

His capacitor is toast either way

The capacitor is probably still good, but on borrowed time due to the over capacity (too high voltage). So ya, definitely replace it.

 

Too high voltage?

 

Put that capacitor in and measure the voltage from the positive side of the capacitor to the chassis ground.

The dents are from the manufacturer.

Make sure to measure the voltage with the capacitor installed.

You won't need to run it too long, just long enough to get a voltage reading.

Thanks for the advice everyone. Measured the voltage from the positive side on the capacitor and was reading around 100 volts when running. Quit running when testing and haven't been able to find that cause..but would the high voltage reading be a result of a bad capacitor or stator?? Is there anything else that could cause that? Thanks again guys!

A leaking capacitor is toast, so that needs to be replaced regardless.
I may be wrong, but I'm pretty sure that if 2 of the 3 windings are shorted together higher than normal voltage may be produced.
Hopefully it's your stator; otherwise, it's your regulator and that's in the ECM $$$

I've got a new capacitor on order. Is there a way to test the stator? If that checks out it must be a bad voltage regulator? I'd imagine that's dealership work as you'd have to reprogram the ecm.

Yes
Check all 3 windings (yellow wires) for continuity (there shouldn't be)
Check all 3 windings for continuity to ground (there shouldn't be)
It's more detailed in the service manual
PM me your email and I'll send you a manual

Also, if it is a bad voltage regulator would it be possible to swap a new ecm entirely? They aren't too expensive on ebay for a used one, compared to what the dealer has them listed for. The ecm would be pretty simple to swap, just not sure if there would be any additional programming needed.

100 Vdc?

 

Wow, I did not expect that.

 

I think this merits an ECM swap before it fries any electric components.
