To the battery, ya' got your white wire and your black wire. If my logic is correct, as opposed to AC, the white wire connects to positive and the black wire to neg. So far so good?
My further problem is that yesterday morning, in the midst of a thunderstorm, shore power was lost. That's when I discovered that I have no DC. I have 2 batteries that I maintain regularly, but only one connected to the rig at a time. They measure respectively 12.84 and 13.11 DCV. I connected both in turn. Zip, zero, zilch coming in. And yes, I pulled every single fuse and cycled every breaker. Continuity checks out across the board. With AC connected, everything works.
What am I missing? Thanks in advance for any help
That would be rather unusual. I have only seen red to positive and black to negative.
Follow your main battery cables and look for a shutoff switch, main fuse, fusible link, rusted connection, etc. and check where the break is. If you can, use a 12 volt light bulb to check the voltage - not a voltmeter which can indicate voltage even if the resistance is too high to let much power through.
