Can you call your coach builder ans get your DC wiring schematic for your make and model?
I got the water heater working. Yes I did test both the supply and fused side of the circuit and it is and was powered. There is something within the multiplex system causing the loss of power to the switch. I unplugged power to the multiplex cpu and replugged it in. When I replugged it back in I got a very strong flash of light and a pop. None of the lights in the coach worked for about 2 minutes then everything went back to normal including getting power back to the switch. Water heater working. I'm going to call REV and ask them for info on the multiplex system.

Yes only one switch that controls power to the relay and it's located below the bathroom sink. However there is a separate push button switch to start the propane portion of the water heater located on a multiplex panel which also has several other light push button switches and a fan switch in the same panel. Next to that panel located in the kitchen area is the no fire propane light.
I'm attempting to get info on the multiplex system and how it controls the water heater and what ever else it controls.
Thanks guys for helping me on this. I'll post further info as I get it.
