Was riding the other day and while just cruising down a gravel road at 30 mph the quad turned off like I turned the key off. Everything went blank. Tried to turn the quad back on and nothing. Gauges are blank, no lights, no clicking. Nothing. But I do know that the electrical selector switch is good because I do have power to the winch with the selector switch in the on position and no power when turned off. I put in a new ECM and no change. Any suggestion.
