I purchased a new solenoid and control with sniffer by trident last year... installed it and it did not work. Had to send it back for a new one.
Installing it was a real learning
experience as I found that the wiring
to it was bad, corrosion
, non tinned 28 year old wire.... then realized that the propane line was non grommeted and poorly installed. When I bought the boat I noticed that there were some work to be done for sure in the propane locker, but it opened my eyes a bit to propane on board.
My feeling is the solenoid switches are to delicate for that wet of a application. A propane locker on deck
, or below deck
as mine is, is not really a good place for wires and electrical appliances
. Probably just safer to go on deck and open the tank by hand, and shut if off when your done.
For me, I think my propane use will only be for grilling now, and then its a matter of just reaching down, opening the locker, and twisting.
