Seems like my isolator is frozen shut on both circuits and is passing
current to the rear battery cables (with the combiner disconnected).

The GMC MI Parts Book shows three models:

Sure Power (70 Amps), (95 Amps) and (120 Amps).

Which do I need for a 1975 GB with 30 amp camp ground service?

I can rebuild an engine but know nothing about DC electricity.

Thanks-

Jim "Doc" White
75 GMC Stretch (with new big ass Mac Dash and GPS radio)
