    Polarity is a good call, I had issues when I put mine in with the polarity being reversed inside the fixture. So one worked, one didn't.

    the lights work on battery = proper polarity.

    A volt meter test of wire on the back, probe the blue 12v+ output and white - with the conv-off-batt switch in various positions. If there is no 12v while plugged in to 120vAC the converter portion of the power center is bad but the 120v is still working.

    Generally the 15A 120vAC breaker is the circuit that powers the converter and the inside outlets, the 20A circuit is for the air conditioner outlet. The fuses are for the 12vDC circuits.

    Using a battery charger anytime you have 120v power to 'act' as the converter, connect it to the battery.

    I finally opened up the wiring and this is what I've got -

    Red wire from light to blue wire on camper and black wire on light to white on camper. Does this seem right? I've worked a lot with wiring at home but not in a camper and have no idea what a blue wire does. Is that the live wire?

    That makes a lot of sense, I couldn't wrap my head around why they would work on battery if polarity was wrong. One more reason to replace the converter. Sigh.

    Blue is + coming out the back of the converter via the safety switch, white is the neg.

    if your battery is hooked up correctly and the lights work via battery the polarity is correct.

    For DC red is usually + with black as the neg.

    Other schemes have black as + and white as neg!
