After years of working fine my fridge now has a problem. It's an 83.5 Westy.
It runs fine on A/C and battery but when I run it off propane the flame
lights but it then runs off the battery instead. I discovered this when I
hit the battery/water level light after being camped for about 1.5 hours.
The battery was in the red.  I disconnected it and I heard the fridge shut
off. I double checked and it was set to run on propane.  I shut if off and
waited a few hours. I then started the fridge on propane and left the
battery disconnected. It never got cold.  Any suggestions?

Thanks,
Bryan
