1st - I have 2 wires going to my battery + now and one of them tests 12+V when plugged in.

You may have the battery connected backwards!

Your Casita when new had only had one wire, a BLACK one, on the POSITIVE battery terminal.

And a GREEN wire and a WHITE wire on the NEGATIVE terminal
The green goes to frame ground on the trailer.

The charger in the converter connects to battery voltage in the converter.

I had it typed backwards. I do have it hooked up correctly! All seems to be good. Thanks!
