I snaked the little wires from my installed digital DC volt meter... The display is under the sink on a toggle. The circuit breaker (AC) & fuse (DC) converter is in the kick space below this. I wired it to an open fuse (why is it open... only a few of the 9 slits are in use?) It didn't work. I unfastened my connections, clip lead to the DC mains, it works. Whew! I didn't toast the unit.
Yes, same unit with salvage title.
We are not RVing with it, we stick to the basics. Lights, fridge, stove, furnace, water.
I shut the AC breakers off when I was working... DC shut off is on the bottom of the box on the tongue (3 group 24 RV batteries). I am thinking that was it Mike's idea on an inside DC switch is a good one. Where to put it? Needs more looking. Maybe though the shelf that separates the electric compartment from under sink.
More later
