HI everyone! I am having an issue with my Atwood furnace (7916-II) in my 98 Coleman Santa Fe. Here's the problem: When utilizing the battery (12V) to power the furnace, the blower spins, the igniter clicks, but ignition does not occur. (I have a video, ill upload it later) When plugged in to 120V the heater starts as normal. I have notice that the blower runs significantly slower utilizing the 12V power supply. Things I know: I have a full LP tank, and I have a brand new (load tested) battery (I have used a different load tested battery from my boat and achieved the same result). I don't know where to start the check process as I have never touched the insides of a heater before. I have (and have read) the manual, but with the furnace functioning normally on 120V, I didn't any solutions. I am currently thinking a loose ground or Power connection (on the 12V side), but I would love to get some advice from others if they have any input.
