maybe someone can help me with this...i am a tech but i dont usually work on polaris this is my uncles atv, but this seemed to be a universal problem the bike starts to cut out right off idle and clears up when you turn the lights on or some other type of load...and it is charging at 15-16 volts...on any machine that means regulator is shot....so i changed it...now it is charging at the normal 13-14 volts but the same problem still persists and clears up when you turn the lights on or if you unplug the stator charge wired going to the regulator/rectifier.....maybe there is somthing wierd i dont know about polaris so im hoping someone can help me out here...i also know that the battery is dead but he has 2 400's and the other on is dead too and still works fine...again i noticed that when bouncing around on the trail the dash flickers on and off but i found no loose connections....purely stumped lol
