The furnace will not trigger the propane heat unless the air flow switch is triggered so apparently not enough voltage is getting to the fan to spin it fast enough to trigger the switch on battery, but when the converter kicks the voltage up to charging levels the fan spin fast enough to trigger the switch and consequently the propane heat comes on.

That seems to fit the facts. So, are my batteries weak? New batteries?
