AllegroD - I believe the AC is separate from other circuits (Fridge, appliances, etc). There is a double 20 amp breaker (20 + 20). The AC seems to be for one, and the main for the other. Then there are two other single 20 amp breakers for lights and appliances.
RCMAN46 - the voltage before AC is on at all is 120.6, with only the fan on it's 119, and with the compressor on it's 109.5
So the compressor seems to be pulling about 10 volts. Is this normal?
I've tried a couple new breakers and cleaned the coils 2x in the last couple of months.
I am on a 30 amp plugin. I'm thinking it might help to check the wire (from Motorhome to power box) before I conclude anything. I'm guessing I can use an ohms meter to test the wires and see if there's any resistance.
From what I can tell, it seems like either a bad wire or a bad compressor, but I'm no expert. Thanks for any other suggestions.
