CJ5 wiper motor problem
My wipers have been working intermittent for the last couple months. Not a daily driver so I never really looked into it. Tested power to it, and found that the PO decided to use a wire nut to repair a broken wire. thinking that a proper splice with heat shrink would fix it I was wrong. My question is does the motor ground through the mounting surface? if so, the jeep is almost 100% fiberglass so should I explore other ground options. Also, has anyone ever bench tested these units? How if so?
