Loaded question - No battery installed

Erika, can you "borrow" a battery from another vehicle or friend and put it in as you remove the first battery and then remove second battery. This would keep you energized until you got the new batteries?

Our park is small and I don't think anyone would let us borrow a battery, but a good thought. I guess in theory we could borrow one from our truck if we took our small SUV to go get the batteries.

I've always thought that the battery(s) needed to be connected to complete the circuit.

Unless you're driving to Timbuktu for the batteries, you could leave your rig unpowered. Your fridge should stay cold for hours unless the cats open it to get a treat! Other than that, unless it's sweltering down there, the rig should stay comfortable for a while, too. Leave early to get it done before noon.

John,

Your circuit breaker panel and fuse box each have a ground buss bar where all the ground wires for individual circuits are tied down. A ground wire from each buss bar goes to the frame, as does the negative battery terminal. I think the ground wire from the Power Converter also goes to the ground buss.

If your 12V DC devices are getting the 12V from the Power Converter, with no batteries in the loop, the ground buss to frame provides a ground path to close the circuit.

When the battery is the primary power source, I believe the negative post of the battery has to be grounded to the frame in order for power to flow from the battery.

That's how it works in my imagination, and maybe also in reality.
