Is it the Alt. or Volt. Reg. ?
I forgot to add that you diconnect the terminal from the field that you ground to the alt first, (Sorry)
My point was to tell someone how to find out in less than 5 seconds, not to train the OP in automotive electrics.
But hey, maybe the OP want's to spend all day figuring it out.:read2:
I rather like getting to the point and fixing it.
