Agree with post 22.
Several Model A's in our tour group are equipped with AC. Consequently there is a large electrical load, approx. 30amp, constantly. That causes the alternator to charge at a corresponding rate. We noticed the ammeter (30 amp)gets very hot to the touch. (one actually failed) We created a shunt to parallel the ammeter which reduces the visible reading to approximately half the actual charge current. They are working well.
