Good thought, but that's not it. My boat originally had one line from the (enclosed, properly draining) propane locker under the helmsman's seat that then Tee-d off in the boat to serve the stove and the heater. I replaced ALL the propane lines and removed the Tee so that each appliance has a dedicated line that runs from the propane locker directly to the the appliance and the only connections are in the propane locker. Now ABYC compliant.
The solenoid is in the propane locker. If the solenoid is not stuck open (my original guess) then I suppose it continues to get electricity somehow even with the Trident display is switched off. I can try to disconnect the leads at the solenoid and see what happens. I thought I'd get to the boat today to try this but looking unlikely, maybe in a day or two.
I appreciate all the advice and suggestions.
