No lights on 1980 enticer 300 twin... - Snowmobile Forum: Your #1 Snowmobile Forum

This sled sat for several years. I cleaned the entire fuel system and so-on. It runs and starts perfectly but nothing electrical works. No headlight, tail light, brake light, or heated handle grips. I started going through the electrical system, all bulbs are new.
I traced the wiring harnesses and found nothing unpluged. Ign switch is good. I also tried a different voltage regulator and cleaned 1 ground. Is the lighting coil bad or did I overlook something? I did not pull the 30 miles or so of electrical tape off the wiring harnesses. I do have a multimeter to test the lighting coil but not sure where to check the ground. At the black wire coming from the mag or chassis ground? There was a mouse nest in the airbox but I didn't see anything chewed up. I know the wiring for the handlegrips is tapped in 2 inches after it comes out of the motor and they didn't work so I think the CDI mag is bad. Is this common? Its all one unit. I did not check the harness where it goes under the motor but the handle grips are tapped in before that. Any ideas?

Great job troubleshooting, and I think you hit it on the head with the lighting coil. That's all that's left. If it was a ground they'd at least be dim. The grips would work if it was anything else. The lighting coil is a separate part of the stator and can be replaced by itself.

Thanks for the praise!
I am a garbage truck mechanic so I get to troubleshoot all kinds of strange problems. I just never saw a lighting coil go out before. I do have a 78 exciter motor and they have the same part number for the coil but its under the flywheel. I bought a "deluxe master" puller set from Matco tools today and it had a few metric bolts in it. Do you know off hand what size puller bolts are needed? I think this set goes down to M8 but it looks too big. My sleds are not in my yard so I would have to bring all tools in my trunk to service them.
Also please check my post under Polaris with a secondary clutch question. Not against anyone else here but you seem more knowledgable then a lot here.
Thanks
Vic

I don't know enough about clutching to be helpful to you. Small world, my cousin is also a garbage truck mechanic...What are the odds????? I think the puller needs M6 bolts, but that's on Ski Doo. Won't know until you take it apart....I'd buy the bolts anyway just to have them in the kit.

still no lights. I did not get the coil out of it. like I said, lack of tools.
I did however, get the replacement one out but destroyed the rest of the ign system. The puller bolts were M8. I did not know that they were through holes and I screwed the bolts right into the ign coil and the pulse coil. I didn't mess up the light coil though. I pulled the 80 enticer apart with no problem. I learned from the doner sled how to do this. I rounded the 2 coil screws due to inferior tools though. No vise-grips either.
I did check the resistance or both coils though. They both read the exact same .4 ohms. Spec is .2. Is it a bad coil? All I know is that both sleds had working lights at last run(5 years ago). I checked grounds on the one with no lights and all are good. I checked continuity through the harness and was good. dimmer switch is good. It doesn't go through the ing switch so thats good.
What the hell is going on here? 2 bad coils? What did I overlook?
I will put the other coil in just to see what happens but why the same ohm reading?

It does sound strange, but what's left? You've done everything else you can do.
