When the furnace fan stops the 12v voltage does a bounce back. Now the 12v things won't work, but then they do. Does the 12v bounce back too high (how could that be--is there a setting on the ? set wrong?) and trip something (inverter?) then the battery (getting low) takes over? Now 12v voltage lower so inverter works again? They are on shore power. No idea what the converter is really doing. All very mysterious.
