No he hasn't really. He's only proven that the other alternator works correct.
Yeah, he did take HIS alternator to be checked and it checked out ok but I question the type of tester the place used. I say, at this point, his alternator has a bad diode and the bench test that was used couldn't check it under load or check to see if the diodes were good........or both
If the other alternator worked and got the correct voltage readings, why doesn't his PA alternator do the same?
