Battery will supply the 12+ volts needed to run the thermostat and furnace fan. This is how people camp off-grid every day.
You have an open circuit between the battery and the fuse panel or between the fuse panel and the items that do not work. You will need to systematically look for 12 volts along the entire path to find the open circuit. Generally it will be at a junction, fuse, switch or breaker. Generally not mid wire. When you find 12v on one side and zero on the other of one of these items you need to clean, tighten, adjust, repair, or replace that item. If this seems daunting it might be best to call a mobile repair person or haul it into a shop.
Since your lights work I assume 12v power is getting to the 12v fuse panel. Pull each fuse and test with the meter.
Converter is easy. 120vac in, 13.6vdc out. Only trick would be getting to the wires. Need to disconnect from the battery to make sure you are not reading battery voltage. Divide and conquer.
