Nothing comes easy off grid

Spent our Saturday finding, cutting, and hualing wood. Have enough for at least two weeks. When we finished, and started to get cleaned up and make dinner, wouldn't you know it... No power.
So the next three hours was the strangest hrs of the day. With 12v of power at every point in the system, but not a working light????
Turns out to be a faulty main switch...

Oh the fun of off grid living!
