dmorse: I can reach the fresh water, but not the other two. Good thought.

pterrydactyl At the back of the switch, there are three wires to one terminal, and 1 wire to the other terminal. I think you're headed in the right direction, but I don't know where I'm going. But your question tells me - you can tell me how to get there.
Checking the owner's manual, it appears that the water tanks use heat pads drawing 4.8 amps and 65 watts or drawing 5.8 amps, drawing 78 watts, and the elbow would use 1.7 amps and draw 23 watts. If I turn on the switch, and have 4 pads (figuring 2 for the fresh water) drawing 5 amps each (rough average of the two) - plus the elbow, what should a volt meter applied to the battery indicate. Or, worded differently, if only one or two of the had pads work, I'd expect to see different readings than if all four work. Will a reading tell us how many are working ? As all can tell, I know enough to get in trouble.
