06 400 4x4 auto problem
I had a customer bring in his 06 400 auto 4x4 to me yesterday. he said its been parked for a year and won't start. Before that, it wouldn't go over ~8mph and then would die.
I pulled it in, did some trouble shooting, and there was no spark. I narrowed it down to a bad coil, but I can't shake the feeling that there's something else causing the lagging. I don't have a peak voltage reading adapter so I can't test the input voltage to the coil. Are there some tests I should run to test the stator? Rectifier/regulator? CDI?
I have the service manual and it's about as much help as a rubber crutch in a polio ward, especially since there's no wiring schematic.

Yes. There are some videos on youtube, showing how to fix. I think a bad stator can kill the coil. I'd be inclined to buy the new improved stator, however, maybe a 2002 one may work. Check eBay, I don't think the fix is too expensive. Sucks, because it's a very nice quad, otherwise. I love my 2002, went out today, howling wind, just above 0F, and it started on the first click.

I'm new here but...
I wanted to fill you in on what I've learned. My multimeter is a fieldpiece. It has a Min/Max option for voltage checking and with Max selected it shows me the max volts being sent by the source & trigger coils. You mentioned not having a peak adapter & I've found nothing on the web that says anything about what I learned of my multimeter. Unfortunately my trigger has no signal for some reason. Hope this helps you in the future.

Continuation of this nightmare: replaced flywheel, coil, and thoroughly cleaned the carb. Ran great. Took it to the customer and he was pleased. Called an hour later saying it runs like crap again. Long story short, I'll clean the carb and it runs great. Let it sit for an hour and it runs like garbage. It's done this repeatedly. I've cleaned the fuel tank, replaced the fuel line, and installed a fuel filter. Nothing seems to help.
