Well my Propane tank gauge has been staying slightly above empty for at least a year. I know there is some fuel still in there. I used both the refrigerator and the furnace at the Shawnee rally the gauge never moved after two weeks. I haven't filled the tank for about two years so it should be somewhere around 1/2 full or slightly less.
Today I decided to find the problem. I removed the wire from the sending unit on the tank and the gauge in the coach went to full scale one way. I then jumpered the sending unit wire to ground and it went full the opposite direction. So the wiring and the inside the coach gauge are working. (I forget which way is full and which is empty).
I removed the sender and cleaned the mounting (ground side) and also the terminal where the wire goes. I put an ohm meter across the sending unit and with a magnet across the back I moved the gauge from empty to full and back again. I got the expected readings between 0 and 90 ohms. So the sending using unit also looks good.
Not knowing exactly how much fuel is in the tank I set the gauge to 1/2 and remounted it. Now that it is mounted it still reads 1/2. If I remove it and set it to 3/4, then it stays at 3/4 when remounted.
So here is my question. How do I get the sender to re-sync with the float (and magnet) inside the tank?
I plan to go for a ride and bounce the liquid around inside the tank to see if that helps re-sync the float to the sending unit again.
