Perform these checks with shore line connecter or generator running. Measure all voltages relative to ground. The problem could be:
Bad batteries not accepting a charge. Verify at least 13V at the batteries. If there is, then the converter is good but the batteries may be bad or the connections are too dirty. Clean the connections and see if it helps before replacing the batteries.
Bad or dying converter. If 12v systems (lights, thermostat, etc.) work when plugged in, converter is probably ok, but check output voltage to be at least 13v, enough to charge batteries.
Disconnect solenoid that is operated by the disconnect switch is failing. This is the item that clunks when the switch is pushed. When batteries are on, there should be at least 13v at each of the 2 big lugs relative to ground. One lug is connected to the batteries. The other goes to the converter.
Last check is the inline fuse or circuit breaker. It will be inline in the positive cable from the batteries. Again, should be at least 13v on each lug relative to ground.
Good luck.
Oh, and be sure your volt meter measures colonial volts and not imperial volts - kidding.
