have a 2001 500 magnum polaris. great machine, but have a intermittent short or something and cannot find it. it's been to two different dealers in the last two years and neither could find the problem. it only shows up after it has been running for about five or ten minutes and you really only notice it when you are attempting to ride in the dark as the headlight starts cutting out. it isn't a short between the battery and the ignition switch because it doesn't drain my battery when it is off. i have torn the thing apart looking for a bare spot or worn spot on the wiring harness and cannot find anything. i have had the plastic off so much it doesn't stay in place without bandaids. anyone have an idea???
