GlennLever, excellent post here and exactly the topic that I was looking for. :)
What became of getting your "electric only" function resolved for your water heater?
I fulltime in my 2002 Winnebago and stay on my sons property. I don't take the motorhome out very often for the time being and I don't want to deplete my propane on hot water when I am plugged into 30 amp 120v full time. I want to keep my propane available for cooking only. I heat the coach with 120v when needed too.
So I want to use my new replacement 4E water heater on electric only. This will allow me fewer trips to have my propane tank refilled and also prevent me from having to buy into the "stay awhile" portable tank propane source should my builtin tank run empty at a time I don't want to move/drive to a refill point.
I'm parked and set up on a slope requiring lots of levelling blocks and it's not so easy to just raise the jacks and go.
I also wish to keep my existing switches functional and avoid installing the new dual switch the new water heater came with which would have to be installed on my water control panel inside the basement compartment next to the water heater compartment.
Have you found a way to separate your white and orange wires to gain the "electric only" feature by utilizing your existing indoor coach switches?
As I search the web for answers I have found one forum member on a different board that had a tech accomplish this on a similar Winnebago but the owner has no idea how the tech actually wired it. :(
So currently I have not wired my water heater yet.
