swphoyobug, yes I called Forest River who told me that unless I knew who built my 5th wheel or who wrote those labels they couldn't help me.
2oldman, the bigger picture isn't much bigger but it can be zoomed in on. I can't take any larger of a photo. I was literally 6 inches from the panel with my camera.
joebedford, Thank you. I knew the heater needed 12v power to spark the propane when using it that way. I just couldn't make out the writing. The Water Heater worked fine before this past weekend. I'm thinking the breakers tripped. I'm at a loss why. When I plug in to the pedestal, I always make sure the breakers are off and turn those on last after all connections have been made. I thought about Gen and Gen D too but I don't have a Generator.
BB_TX, Yes, the Water Heater connections give me 120V when the breaker is on and the switch is on. I emptied the tank and took out the heating element so I could test Ohms and Volts and determined no other problem exists.
houstonstroker, I'm back home and don't have a 50A connection to see if there's an issue with one of the leads. I just have a 20A plug with a dog bone so I can't turn on a bunch of stuff to test.
