1996 Coleman Yukon: Atwood 7916-ll Heater. This is my first popup, and it came with no owners manual, so I have had to rely on the little bit of info I can find online, and just good old common sense. I am having a problem getting the heater to fire up. I have: - made sure I have 12v min at battery. - turn on converter to 12v - turn on propane - turn thermostat on & set at lowest setting From what I understand so far, is that now I should be able to turn the on/off switch on the heater to 'on' and the blower should kick on, which triggers the 'sail switch' which tells the unit to fire-up. When I switch the heater 'on' nothing is happening. I got my test light and found a constant power lead that goes into the side of the heater, and immediately into what looks like a circuit breaker (says 5 amp on it) and continued power out of it. The lead then drops down to the lower section of the heater and blade connects to what I am guessing is the 'relay switch' - 1 blade power in, and six blades coming out. I have confirmed power in, but no power is coming out on any of the 6 blades. One of those outgoing blades runs straight to the 'on/off' switch, which means the on/off switch is not getting any power in the first place, which must mean that the 'relay switch' is defective!!! -- right??? - Whats your thoughts? thanks.
