I had my alternator rebuilt twice by the shop I have used for over forty years. The first time it only lasted about a day and a half. They took it back and said it was a bad ------, I forget. Installed the rebuilt rebuilt and went for a spin today ebatttery light came on. So it is going back again on Monday. But I do have a question, can the two plug ins wire harnesses be plugged in backwards? I have to say that th struck is a '87 250 but I get better answers on this branch of th Eco rum. Thanks.
