Electrical-not converter?

I thought my electrical issues were the converter, now I'm not sure. My question is: I am plugged into shore power, running AC and some lights with the battery disconnect switch on; when I disconnect the battery, the lights and AC go off. I don't remember this happening before. It seems that I ran off shore power with the batteries disconnected. If it's not the converter, what could it be?

Your thermostat runs on 12V, so if you take that away, the AC will shut off.

At least that's how my trailer and my motorhome were...

According to my wiring diagram, the 12 volt disconnect switch removes both the battery and converter from the fuse panel which results in all 12 volt systems turning off. As mentioned, the wall thermostat is 12 volts so it would turn off anything it controls.

Why are you wanting to turn off the disconnect switch. The only time I ever turn mine off is when the rig will not be used for months.

I'm not sure why I wanted to turn it off. Maybe figuring not to over use the batteries?? I am not electricity knowledgeable at all! I guess I just got lucky last year that everything worked, I just want to be sure I am doing the right things. Wasn't sure I had cooked my converter which fried my coach battery and would like to prevent future mistakes!
Thanks!
