Just thought of something else I read earlier. If I turn OFF the battery disconnect switch and stay plugged in to shore power the 12v lights go out. If the converter is working shouldn’t the lights stay on with shore power?
Yes, IF the converter is also getting 120v input while other 120v things are. You can check for that too.
EXCEPT--if the converter is on the other side of the battery so it supplies the 12v fuse panel across the battery and uses the same wires to the panel as the battery, so now the disconnect will cut off the converter's 12v too.
