My "information center" showing battery charge and tank levels has worked great, until the last propane fillup. Since then, it has always read full. At first I chalked it up to summer use- that it really was still full, but it took 8 gallons today, so I know it was pretty close to empty.
So far, I've confirmed that the wires going to the propane tank are connected. They are. I can continuity test the wires to make sure they aren't broken from the info center to the tank, but have no idea what else to try. Anyone know?
The propane level potentiometer is typically magnetically coupled to the float inside the tank. Take part pick up magnet see if you can move the tank dial around.
Haven't specifically looked at the LPG level indicator, but the tank senders all have a local ground connection. You should probably include that in your checks, as it's usually the first connection to fail under the vehicle.

Just so we're clear on what we're talking about, is this a removable vertical (DOT) tank, or a permanently mounted horizontal (ASME) tank? I don't know when LD switched, but my 1985 had a DOT tank with a nonworking sender of some kind.
Permanent horizontal tank. 2 wites, red and black, going to the tank, both appear solidly connected
Here are a couple ideas, like Rodney said above it could be a stuck indicator or bad gauge.

Thanks. I don't have a gauge mounted on the tank, but the sender should operate off the same principle correct?
Jeff,
Please post a picture of the gauge. My 1988 Mid Bath has an ASME horizontal tank and a permanently(screws) mounted gauge . My Class B has a 2004 tank with magnetically coupled snap on plastic indicator.
With the wires removed front tank's sensor, what resistance do you measure?
