When I have the battery disconnected I am showing 13.8 volts on the wires that go to the battery. I don't think this is possible but it looks like I have electricity running to the battery but not back to the converter. Any suggestions? Thanks

Not familiar with you particular trailer but below is the basic Rv converter operation.
Electricity does not run
from the battery
to the converter. The converter is powered by 120 volts. The converter supplies 12 volts to the RV 12 volt buss fuse system. The converter also charges the battery when it needs it. 12 volts runs from the battery to the 12 volt fuse buss system. The 13.8 is the charging voltage
to the battery. The 13.2 is the battery voltage.
When you unplug from shore power you turn off the converter. No 12 volt supply from the converter to the 12 volt buss bar. At this point the battery
should be providing the voltage.
There are 2 "reverse polarity" 30/40 amp fuses between the battery and the converter. There is also a resetable main fuse inline within 6' of the battery. You need a volt meter or probe light tester.
Since the lights go out when you unplug the shore power there is a fuse out between the battery and the converter.
