Is the voltage regulator grounded via a wire ground or the screws holding it on to the frame/tunnel? Mine seems to be flopping around barely hanging on to one screw, of couse im having electrical issues with my sled at the moment, wondering if this could be my problem. By the way, trails are open with 5-7" of groomed base with system snow coming in tonight with accumulations of 12-15" then lake affect snow to follow, love living in northern Michigan! Ride on!!!!!
