So I uninstalled, cleaned and reinstalled the t-stat. I also drained and flushed so I could put the air gap back in the top of the tank. Before I fired up I checked into the electrical side. No AC volts at element and 10.68 DC at the yellow wire. Seemed a bit low so I checked into my 12V system. Batteries at 12.68 and DC to board is the same. When I went from the 3E to the 4E I had to tap into the 12V lighting wiring in the storage to get the 12V constant for the white wire. Element tested ok. Turned AC power back on and no AC out of relay. Replaced relay. Buttoned everything up and turned AC and propane back on. Hit 140 in less than 20 minutes. Hit 150 just short of 30 minutes. Was going to go out and ohm out the t-stat and then I heard the propane shut off. It looks like 150(ish) is the sweet spot for this new t-stat....Thanks for the help! Everything appears to function like it should! For now.....
