Heavy Duty Alternator

I put an alternator for a 85 New Yorker on my 69. You have to ground one of the field terminals to the body of teh alternator. It is also recommended that you upgrade the wire going from the alternator to the ammeter.

The one on the donor motor may be similar.

P.S. Just checked, same alternator. I would not run the 100 Amp or higher version. It would most likely be too much anyway and it is larger and heavier.

Why did this happen?????
