Thanks everyone for the thoughts!
Neschultz; there's 12v at all time. My domestic battery is actually completely isolated from my vehicle battery; the alternator does not charge the domestic battery.
I wasn’t clear enough. The 12 volts from the alternator to the refer did not operate the refer or charge it. It was a logic voltage that allowed the use of the TT 12 volts to operate the refer. It probably operated a relay. The refer would also not run on 12 volts automatically...you had to manually select it. When the engine stopped, it would revert back to AC or LP automatically.
Definitely not, the only low voltage wires into the fridge are +12v and gnd. Those lines will run a 120vac inverter which I can run the fridge off of (my workaround last year due to no 12v operation) whether I'm running the engine or not. They have 12vdc at all times.
