Alan...I understand what you are saying, but how is it different jumping the #2 wire straight to the Batt terminal vs the way you described above? The voltage reading would be the same at either point...no? The only real difference I could see is that if the #2 wire reads voltage at the alt you eliminate any resistance that is in the #1 wire. If #2 wire reads voltage at terminal 1 it should be the same with the exception of a miniscule (probably undetectable) drop due to the length of #1 wire. It would seem to me that jumping the wire to the Batt terminal simply uses less wire to achieve the same purpose. In fact I don't really understand why this isn't done internally to the alternator.
Not trying to be difficult, just a little confused.
