Angry 12 Volt light problem

I own a 2017 RedHawk 23XM, I am having a problem with the 12-volt lights. They only work using the battery. I have changed to converter, and I am getting 120Volts coming in and it is converting it to 12Volts checking with an ohm meter. My question is there a fuse or something Im not checking. Question two should the 12-volt lights work if the battery is dead while hooked up to shore power? Im getting ready to dig into this thing and fit it and need all the info I can get.

Electrical is always fun.

Question 2 is easy. If connect to shore power, all your 12v will be power through the converter.

Question 1, I'm not familiar with MHs they are a bit different than a trailer. I would contact Jayco with your Vin number and ask for the 120v and 12v wiring diagrams.

I would check that all the 12 volt wires have been tightened at the distribution/fuse box including the ground bar. I found all the ground bar screws had not been tightened and a couple of the distro box were loose.
Just a start!
When plugged in you should be seeing a higher voltage at the battery indicating the charging circuit which also powers everything when plugged in is working. Should be higher than when just on battery. Simple test to start.

Here is a shot of the wiring diagram. Question - does the converter charge the battery? That can be verified by measuring across the battery when plugged in. Should measure mid 13s to mid 14s.

Looking at the wiring diagram, there isn't much that could go wrong in the circuit. The converter feeds straight through to the fuse panel through the battery cutoff solenoid while the battery goes though an in line circuit breaker to the cutoff switch. Given that the battery works that would mean the cut off solenoid is functioning.

In my opinion there are only a couple of possible failure points:

1. The converter isn't putting out what it should. Measure at the converter. Should be mid 13s to mid 14s depending on what charge state it is in. If nothing coming out, verify it is receiving 120 volts in. There is a circuit breaker for it that you can cycle.

2. If the converter measures OK, then there is a break in the connection between it and the rest of the rig. Check both positive and negative connections. If the converter connects to the metal chassis, that could have broke loose.

Having a dead battery could prevent the converter from putting out. If you had a dead battery the lights would not work. If the battery is really in bad shape it could prevent the converter from putting out any charge voltage as the converter would see the dead battery and stop in its tracks. It all depends on how bad the battery is.
