I wish I could take pictures to make this easier to explain.. But to clarify a few things... I am hooked up to 30 amp power. It has a newer LP detector installed already, it is a Safe-T-Alert LP detector. It is dated for August 31, 2015 When I got the motorhome and it was not plugged in yet, the LP alarm was going off..but the gas was off and it was displaying a red light which says it means either low power or end of life.. I have a battery I can maybe hookup to test today... Where is the shutoff solenoid? Somewhere past the 2 stage regulator on the low pressure side?Hooked up to shore Power, but LP detector isnt working..Hello, I just bought an older 80's vanguard motorhome..I'm a first time motorhome owner.. When I got the motorhome I was being shown around and although we didnt light the stove, the LP detector was illuminated when he turned on the fridge.. The next day I come back to the motorhome and the LP detector is red and making an alarm.. the red seems to mean it was a low battery..I checked to make sure the propane was off and that was that. I didnt do anything else other than move the motorhome and I connected it to shore power. Now the next day I come back again, and the fridge isnt working. The LP detector won't turn on. And I dont have propane to my stove top... I'm here asking if anyone knows what is wrong because I have tried Google searching.. My results make me believe that if my propane regulator wasn't working, my LP detector should at least be working and telling me there is no gas.. And if my LP detector isnt working, shouldn't I at least be able to light my stove top? Since I'm hooked up to shore power, shouldnt the LP Detector be working, even if there is a low battery? I'm not sure what exactly the do, the OP detector is less than 4 years old. I've read that maybe it's my converter since my shore power is running the rest of the motorhome but is not running the lo detector. Or I'm thinking maybe it's a loose connection from when I moved the motorhome? Any ideas?
