Well, the electrical system was rebuilt in the mid 80's. It has a six volt alternator on it, built by the leece-neville company of ohio. It also has a rectifier on it, assuming that changes from ac to dc current? it has multiple wires coming out of the alternator, maybe six total. 3 leads to the recitifier, and one major ground i think, and 2 small wires not sure what they do. its a big alternator and i will take a pic if some of you want me to. an i can do the electrical system pics to.
