Hi All,
My brother has a 66 Mustang and it is pretty much completely restored except one of the most important things. At least that is what I told him after he spent big bucks on the resto. Anyways, he is having an electrical nightmare. He replaced the solenoid, and alternator. The starter is good and the car runs good after started. When he puts the negative cable on the battery he says it is arching a whole lot (described it as if he were welding almost) and cannot figure out what is going on. He has a voltmeter hooked up that does not work. I told him to completely remove the volt meter wires from end to end, because that is usually one of the main problems because they carry allot of juice. He also said when he tests the positive side of the starter with a meter that he is getting resistance (should he be getting a grounding type of resistance from the positive side). I think he was using an ammeter or ohm meter. I further told him it could be anywhere in the ignition wiring. Is there something that I have missed or is there something that is typically wrong with that year Mustang. I know the older Mustangs typically had electrical and overheating problems, but the three Mustangs I have owned 68, 69, and 71, didn't really have any significant problems. Any advice would be greatly appreciated. He is getting pretty frustrated with his new project and really want to start enjoying his Mustang...
Thanks again John
