We are having to use our furnace....seems fine...gets going, heats, heat shuts off and blower continues for a bit. It seems that this is happening when our blower shuts down....we lose power. Everything but the coffee pot, microwave and TV has no power. It stays off for a few minutes, then comes back on. When it does come back, some of (or all of) our touch lights come on...waking us in the middle of the night last night....and it's still happening tonight. Any ideas? We are hooked to a 50 amp with surge protector
What it sounds like to me is that the furnace is pulling the batteries down dead, and then everything shuts off. But if you are plugged into shore power, all your 12V systems should be powered by the converter.
but they show full with that battery disconnect turned on so we still may just need to unplug the whole camper?

We just cut power to the whole camper and checked batteries and they showed 1/3 and that quickly went away, too. So...changing those today.
Here's the thing - if your rig is plugged into shore power, even with bad batteries you will show 100% on the internal battery charge display. That's because your converter is putting out 12V from shore power. But I don't know why your power is going out if you're plugged into shore power.
The fact that you disconnected from shore power and your batteries dropped down to 1/3 and died tells me that your batteries are dead.
Most converters charge the batteries, so I'm surprised your batteries are not getting charged. How long have you been plugged into shore power?
In any case, even if you remove the batteries entirely if you are plugged into shore power your 12V systems should be powered by the converter. There may be some systems that won't function if you remove the batteries but I'm not sure about that. I think the converter should power 12V systems (via 120V) even if there are no batteries or if they are dead.
