Run that from inverter on house
thanks, but I don't have an inverter on the house battery; only a converter / charger.
I was able to fashion a socket to socket cable using 12v plugs that goes from the house powered TV panel socket down to the engine batt powered dash socket. Tricky getting polarities right reversing end to end.

Hard to parallel the batteries from inside instead of external jumper. The Ford isolator is ignition controlled. I suppose you can go through the emerg start somehow--Class C in sig doesn't have that so don't know how.
Easier with a Chev via 7-pin where 12v is always on with engine off.
