problem started when key was accidently left on. Battery ran down. Friend hooked up charger did not realize it was on 60 to 200 amp boost setting.he says he did not turn key on or crank it while it was on that setting but i dont beleive it. Are there any other fuses or fuse links on this model or just the thermal breakers in the plastic bags under the front cover?

Also is there a kill of some sort if the oil is too high or low? oil appears to have some fuel in it. I assume he left petcock on it reads over full but not alot. wondered if there is a lock out of some sort. running out of ideas

new rmstator kit uses red and black plug in but leaves other stator plug un-used I dont get how that works. I assume there is more than one stator winding and the other winding goes to regulator to provide charge to system. it says that this kit changes from ac to dc system that is similar to what polaris adopted in 2004.

Hi, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, let's review/check the basics for a no-spark symptom. Proposed preliminary tries (if have not been done):

  • • temporarily disconnect the CDI's black KILL wire;
  • • when attempting to start, check for low pulsating voltage from the pickup coil;
  • and high pulsating voltage from the exciter/capacitor charging coil.

Also no "...fuse...fuse links...thermal breakers...oil...lock out..." that can cause no-spark on this particular model.
