simple newbie question , refrigerator
If using my fridge on propane how long will the battery last? Does it draw the 12v from the chassis battery or the house batteries? Will be dry docking for 3 days and Im wondering If i should run ...

I checked the inverted but that only changes the 110v do 12v at least
that's what I read. I also disconnect the (2) 110v power cables on the back of the fridge.
This morning they are dead again.. I'm at a loss
Sorry, this is really difficult to understand.
An INVERTER changes 12 VDC from the batteries to 120 VAC.
An INVERTER/CHARGER does that plus charge the batteries when it receives 120 VAC from either shore power or generator.
The refrigerator PC board works ONLY on 12 VDC. If the refrigerator does not have 12 VDC, no heat source will cool it. Said another way, the refrigerator must have 12 VDC as well as a heat source (120 VAC for the electric heating element OR propane).
Many LP detectors also control a solenoid at the propane tank to shut off propane with the detector off. Don't know if this is what you have, but a quick look at your propane tank will tell you.
