Thanks for the advice.
I went back and measured the voltage drop across the latching relay and both sides to ground and they were both around 3.5V. I also measured the voltage drop across the 50 amp DC breaker and both sides to ground and they were both around 3.5V.
There must be something between the WFCO converter output and the battery disconnect latching relay along the 6 AWG red wire. Is there another fuse somewhere I dont know about behind the converter box? None of the fuses seem broken inside the converter.
I cant trace the 6 AWG red wire too well back into the RV b/c its bundled inside a wire loom.
I pushed on a few various wires to see if something was loose and they all looked good.
I removed a drawer underneath the counter so i could see the wire loom going from behind the converter to the battery compartment.
I do have a AMP meter clamp on my multi-meter so I can use that to trace current but its hard to clamp on some of the wires.
Thanks for the help so far-
