Different charging system on the early A's. The original alternators only had one field connection. My '66 Valiant is wired the same way. When you use the later 2 field alternator you have to ground one of the field connections.
Thank you for the info. Are we still able to upgrade? I was looking to put in a 65 or 100 amp. I know we need to add some extra wiring so we don't burn things up.
