I first noticed the issue several years ago and made a patch but I would like to fix it right. I seem to have lost the ground for the wiper motor, the turn signals and the door chime. I ran a wire from the wiper motor case to the fender ground and have been ok for several years. The wire finally broke at the eyelet and now I would like to find the real problem and fix it correctly. Does anyone know where the wiper motor grounds to the frame?
