Voltage regulator power ? - Snowmobile Forum: Your #1 Snowmobile Forum

I remember reading this on here.. about voltage regulators but I can't find it now.

The voltage regulator regulates the voltage to the lights.....where does the power come from that feeds the voltage regulator?

Lighting coil??

Original problem was the lights were blowing, confirmed with a meter that 32v was being sent to the lights. Determined voltage regulator was the problem but the guy didn't put one on and went for a ride. He told me the left hand warmer caught fire.

Now no power coming to voltage regulator.

I found this pic, I guess it answers my question.

Now, what kind of work is it replacing it?

Gotta pull the flywheel to change the coil.

Thanks RJ.

I don't see any lighting coils on ebay, so I guess the whole stator needs to be replaced.

This should be an interesting repair especially with the motor in the sled, and the sled is so low to the ground.

Ill check tomorrow, I may have a spare coil.

I would certainly replace the coil before replacing the entire stator plate.

Ok let me know, btw ... Nice sled you have !

In case you didn't see it, the lighting coil is for an '88 Ski Doo Formula MX

Thanks, she's a tank, but still screams and doesnt flinch towing another sled out of the woods!!

Sorry for the delay, my house turns into a revolving door for family this time of year

I went through all my parts boxes and it would appear the only coils I have for the Formula MX is the stacked pair of gen/ignition coils. There was an unmarked coil in the bin, but it looks like a lighting coil to a 503 stator. Im going to do some searching and see if that is indeed the case, or if is the one you need!

Thanks for looking but the guy that owns the sled ripped the stator apart including the coils .... so basically the stator is now useless. Lol
I told him that someone on the snowmobile forum was looking for the lighting coil that he possibly had, but the guy that owns the sled was in such a hurry ended up wrecking it.

The wrecker close by by wants $275 for a stator. Lesson learned, don't be in a hurry to fix your sled or you will do more damage than good.

Ugh...
Well, to add insult to injury, you can tell him after some research, this is the right coil... Would have been $23.00 shipped

I guess that's just the way it goes
