Lost all electrical, then it came back. What's going on here?
Hello all voltage experts! I had an interesting incident in my very stock and original 1974 Duster and am wondering if anyone can explain what happened. My three speed windshield wiper motor had just been rebuilt, and I installed it this weekend. The rebuild job looked fantastic, and all wiring was correct to and from the motor. As soon as I tried to run it, the motor jammed and then seized due to a mechanical fault in the motor transmission. Shortly thereafter, the entire car went dead, so I immediately turned the wiper switch off. About thirty seconds later, all power came back on all by itself. The wiper motor was still inoperative, of course. Can anybody tell me what happened? It was as if a circuit breaker somewhere overheated, then closed itself when it cooled down 30 seconds later. I'm not aware, however, of any circuit breakers in the main electrical feed. There is a device called a "fusible link" in the main feed by the firewall, but I have no idea what it does. So here's the question, Mopar voltage experts: Why did my power fail, then fix itself and come back on? Why did the wiper motor seizing cause this? And by the way, this is the second time this has happened to my car. Ideas?
