My wife's 400 sportsman runs fine once it's going, but after only a couple days sitting the battery is dead and it won't pullstart without at least enough charge to light the display. I've been over the thing back to front many times with all the plastic off and can't find any burnt wires, loose grounds, shorts, anything obvious. One odd symptom is the headlights and taillight all blew as well. The only similar case i read about someone suggested the regulator rectifier, but never posted the outcome. Anyone have thoughts? Thanks in advance
