Ammeter Battery overcharge

I am no expert but sometimes these old mopars don't get a full signal voltage to the regulator. The regulator sees that as a low battery and sends more juice via the alternator, which can overcharge and burn up the battery.

Yes I believe you do have to go with the 3 wire alternator when you do the electronic vr upgrade. I did. Maybe there is another way I am not aware of though. I had a 3 wire spare so I used it.
