Thanks!!!

Every bronze connector on the panel is ground, except the cigarette lighter. I had the wires on wrong!

Good info on the multimeter, I had tested it but didn't know which should be + (side or all the way in).

Excellent!

:)

I had thought about mentioning the brass color may be positive which would typically follow other electrical guidelines but was concerned not all were marked that way..

Max fuse size also should be selected to protect the wire.

12Ga = 20A fuse..

10Ga = 30A fuse..

While there may be a few exceptions to that rule, it is very wise to follow typical recommended fusing sizes for the wire size in use. You really want the fuse/breaker to pop before the wire over heats and causes a fire.

Just be aware 20A at 13.8V is 276W max your inverter will be able to supply. Might handle a quick surge above that before fuse blows but that should be fine.
