OP here. I had a few problems with my replies. I leave the battery on a concrete floor in heated basement and use a piece of 2" rigid insulation under it. I also had the battery on charge while trouble shooting the camper. Wouldn't that simulate a perfect battery?
Sure as long as voltage gets to the actual item or appliance.
Need 10.5 to 15.0 volts for RV stuff to operate.
Back to just playing the odds here. The items that are not working all have computer boards that measure the voltage. For example if the voltage is too low to run the furnace fan fast enough to vent the propane gas out, the furnace will not fire.
How you stored the battery was good with the foam. I would still look to make sure the plates are covered with (distilled) water. If they are exposed then that's a problem (might not be the real cause, but still a problem.)
Now that you have the meter out, I would check the voltage coming into the computer board of the furnace. Should be the red wire. This will tell you if you got power, and if you do how much. My memory was wrong with the 12.5, it is 10.5 for the furnace to work. Less then that and the fan does not spin fast enough to vent the gas.
spent two days in freezing weather (the town/park lost all power) before my furnace hit the 10.5 magical threshold. You think I would remember that number after that little adventure. :S
