What do you mean by PO wiring? I’m aware that the ammeter should be fine swapping poles, just one more thing that’s “almost right” on this truck. The battery cables weren’t replaced either so the clamps don’t fit well on the posts. Have yet to see if they put a negative ground voltage regulator on. Swapping that to 12v anyways.
My plan is to swap the field coils and voltage regulator and then hide a buck converter up under the dash to supply a 6v bus for the heater, fuel gauge, and whatever else I don’t feel like changing out.
