LP gas tank solenoid

[dreamer]

2000 Holiday Rambler Endeavor Diesel.

I've noticed the LP switch by the fill valve doesn't seem to be working. I would think this solenoid valve would be normally closed. Turning the switch on and off seems to have no effect on the valve, no click, no indicator light. Still seem to have full LP pressure and volume in the motorhome.

Does anyone have a wiring diagram for this system? I would think it would be a fail safe closed valve. Any idea where the indicator light gets its power from? I have power to the valve when the switch is on but no indicator light.

Thanks,

dreamer.

I believe you are correct all around, should be N.C. if no 12V.
You can check vavle by shutting off propane @ tank, IIWMI'd run propane out by burning it off @ stove burner, remove valve, & blow thru it. If you can blow thru it w/no 12V it needs to be replaced. Note that replacing propane fittings requires a propane listed sealant. You can get yellow gas-resistant teflon tape, but I recommend the gooey yellow stuff in the small tube as you get a more bullet proof seal 1st time.

Dreamer, I know in some older Rvs that have the electric LP shut off valve...that valve shuts off only if the LP detector senses a leak. Does yours have an LP detector? If so, try giving the detector a wiff of LP and see if the valve closes.
