1972 alternator is 37A
with AIR its 42A
Motor Home was 61A.

Anytime you increase the alternator output, past what the stock wiring capacity will handle, the wiring between the alternator and battery will have to be replaced. Then the stock amp gauge will cease to function. No big deal as most have too much resistance, in the wiring and connections, to work after 50 years anyway. You can test it by turning on the head lights without the motor running. Typically they will jump a little and go back to 0 amps or not move at all. This is one of the many reasons GM went to a volt gauge instead.
