mine did the same thing, but it was a ground wire coming all the way from the headlight, it melted it but still don't understand why there was a ground wire from there because the headlight is grounded on the front. The wire was too long of a ground so it would get hotter than hell when you were crankin for a while. I cut it back and capped end and good to go. Been buzzin around ever since. So far thats the only problem I've had, other than a couple of bolts fallin off.
