Furnace works on batt power but not shore power...?

I discovered an interesting problem with my furnace: Most of my camping over the past couple of years is boondocking and the furnace runs fine. It will dependably fire up generally on the second spar...

Voltage........need to check what voltage is being supplied to furnace while on generator/shore power and just battery

Voltage should be between 10.5 and 13.5 VDC at the furnace during operation. Low voltage can cause slow fan speed/low air flow and High voltage can cause unbalanced combustion due to high fan speed/excessive air flow
