testing without DC voltmeter is pretty simple to point fingers at least.
Turn on your ceiling lights without being connected to shore power. Your ceiling lights should work.
Then connect trailer to shore Power and your ceiling lights should get alittle bit brighter.
Having a DC VOLTMETER is best way to test.
Without shore power connected you should be able to read around 12.6VDC across the charged up battery terminals.
Turning on your shore power you should be able to read 13.6VDC across the same battery terminals. This is telling you all the fuses are connected between the converter/charge and the 12VDC distribution panel. It is also telling you the fuses are good between the 12VDC Distribution panel and the battery terminals...
If you don't see the 13.6VDC then either there is a bad connection, the battery disconnect switch if you have is open, or fuses are bad between the battery terminals and the output of the converter/charger unit or the converter/charger is bad.
There is a 120VAC circuit breaker on the 120VAC Power Distribution panel that feeds the converter/charger unit. Be sure it is closed. If the converter/charger is ON you should be able to measure 13.6VDC at the DC OUTPUT terminals at the converter/charger unit at all times except when it is doing charge mode operations. Then it may read 13.2VDC, 13.6VDC, or 14.4VDC depending what charge mode it is doing at the time....
