I'd like to post a word of caution here. When you disconnect the battery
in your trailer for any reason, then some time later reconnect, via switch or removing batter, etc. I suggest you be careful doing so. When the battery is disconnected your propane
detector is non-functional. Therefore it's a good idea to take a good smell inside the trailer before connecting the batter or plugging into shore power. Leave the propane
tank valve closed until the propane
detector is fully rest and functioning.
Just a couple of easy things to do that could prevent some major problems.
This isn't meant to scare anybody but simple to remind everybody that without battery power the propane detector in NOT functioning.
