that the 12 volt appliances are not working when on shore power only? 1986 Toyota Odyssey
We took the negative off the battery, to prevent overcharging, because we want to have the motorhome plugged in, with a small electric heater running on the days with freezing temperatures.
I noticed that we have lights and the stove hood fan working, but not the water pump, light panel showing the tank/battery levels, furnace etc.
Those only work, when the battery is connected.
Do we have a problem, or is this the way it's supposed to be?
Edit: Water pump is working, furnace is not. Furnace works great, when battery is connected.
