I am trying to identify what amperage alternator is installed in my truck. Any idea would be great
1989 F250 with a 7.3 diesel
The alternator has an external regulator, 3 wires are mounted on the side, (2 in a connector, and 1 with a heavier gauge wire to a bolt). Alternator appears stock.
The reason I ask is that I am thinking of upgrading to provide more charging capablity and possibly getting rid of the external regulator.
