I'd be very surprised if your unit did not have a battery cut-off switch. The only units I know of that are made without battery cut-off switches standard are pop-ups - and these have batteries out on the trailer tongue.
That said, your battery cut-off switch is on for everything to be working while the battery has any charge left in it. There's only a few possibilities:
- converter circuit breaker is not "on". Usually, the converter has its own circuit breaker on the AC panel. Physically turning a circuit breaker off, then on is the proper way to reset a circuit breaker.
- converter is not providing any DC power, leaving the battery to provide all the DC power. But you should not read 0 volts on the converter battery terminals if the battery is powering the camper DC. That reading really bothers me, and does not make sense unless the battery was disconnected when you took the reading.
- somewhere, somehow, the connections between the battery and converter are not there. A blown fuse or a disconnected wire would be suspects.
If you have a WFCO converter, Progressive Dynamics makes well-repected drop-in replacements for the most common WFCO models. But the converter is the most expensive component to replace, so I would make real sure it is indeed the converter that is not working.
Also, I would consider your battery is pretty much toast, having been discharged as far as it has - probably more than once. Many converters will not charge a dead battery, and may/may not pop the big fuses in trying to do so (mine did).
Last but not least, you need to disconnect the battery - either manually or with a switch - when in storage without being plugged in.
