What Chris said.
What Westend said in your other thread. To me, it adds up like this:
1. anything that is "pure 12VDC" like Lights and TV Amplifier will NOT work.
2. anything that is "pure 120VAC" like any plug=in appliance (vacuum, TV, microwave) WILL work
3. anything that is "120VAC with 12VDC control" (ducted air conditioner) will NOT work
4. anything that is "12VDC DIRECT from Battery" WILL WORK (till the battery runs down). Your RV Fridge falls in this category with its direct connection.
All this until you can find where power is interrupted coming out of the Inverter/Converter/Charger to the rest of the coach, and you have several suggestions where to start.
You really need a METER. Can be a cheap Harbor Freight or WalMart meter, but you gotta have one.
