Monitor panel, 2000 Suncruiser

the sender is usually part of the tank gauge and can go bad you would have to match the one you have. they work magnetically to the tank float replaceable without emptying the tank. propane tank remote fuel level gauge

So according to one guy on there, the sender/float is for the tank gauge, and the idiot light monitor is all about wiring issues if any.

Mex seems to be saying the same thing for the neg side. Clean up pos and neg to get accuracy? On my tank gauge there is just one wire (red for pos) I suppose the gauge is grounded for the neg side on the tank itself to the MH frame to the monitor panel?

Take a swatch of 00 steel wool and a screwdriver to the tank.

Look at the electrical terminals very closely. Are they anything else but shiny new looking? The slightest graying or darkening of copper or terminal causes gauge error. Replace terminals after scraping copper wire strands bright. Steel wool where the wire terminal goes on. Fixed many a gray, black and propane tank sensors doing this.

I don't know if this will help you but they discuss the calibration with a magnet.

I don't know how to fix that. The guys who know all this said the tank gauge is connected to a "sender" to the idiot light level monitor. So somehow maybe a tech can sort out what the sender sends. I have no clue what magnets have to do with it! :)

They said the tank gauge reading is from a float in the tank. No idea where the sender gets its idea how much is in there to inform the idiot lights.

With any luck, those guys will show up here to solve the mystery!

I know that the tank is "full" at 80%, which is where I get my 2/3 light, never have gotten a full light, But I'm getting the red empty light when gauge on tank reads just over 50%

I had a thread on the Class C forum the other day asking about all that. It turned out that the gauge on the tank itself reads 80% or about 3/4 on that gauge, when tank is "full" (as it should) but the monitor level panel idiot lights then shows "full"

Somebody said when the monitor idiot light level does not match what it says on the little gauge on the tank itself, there is a way to line them up using a magnet. Apparently RV techs know how to do that.

The story came out that the little gauge on the tank is way more trustworthy than the monitor level lights.
