Thanks Lee, That was the answer that I was looking for. I was looking for a place today to test my alternator but none has the old hook up. The are all computerized and looking for part numbers and car models. Thanks, I suspected that the one-way diode is burned but the charging 14.5 V confused me. It is a Hitachi alternator with internal regulator, it has also an "E" terminal which I think is ground for protection. I haven't traced the wire yet.
