LPG guage and control panel don't match

Wouldn't "Disc" stand for "Disconnected"? As in a bad connection on one of the sensing wires?

This has happened before and it resolved itself.
Any suggestions?Attachment 26529Attachment 26532

We have a 29m also and "disc" means disconnected. It is not reading your sender. Ours has done this once or twice also, normally whenever we first flip the battery disconnect to on. A few minutes later it will register correctly.

On a side note, I noticed in your post that your blacktank is reading 33%. Is it empty? We have a supper hard time getting ours to read zero. After flushing and dumping multiple 5 gallon bucks down the toilet it will say zero for a few minutes but normally settles back at 33%. Drives us crazy.

Yes it will not go back to zero. It just started doing it.

I am new to to having a coach. Where is the battery off switch? Pic if you can.

Don't have a pic , but it is right by the front door.

Thank you got it.

Mine is in the 3 o clock position, the readouts are not on the same scale inside. As in divided by thirds, empty, 1/3, 2/3, full. Accurate enough. Fill it when it's cold out, you get a little more in.

In my Class B the gauge in the LP tank is half way under the rig and impossible to view. I have had trouble several times in getting the tank filled much past 50% - I guess because of the small size. The last time I used it for two weeks (running the furnace at night) (inside gauge read 1/4) and the guy filling the tank put in less than two gallons and said it was full. The inside gauge (unreliable at best) then read 1/2.

My question - is there any problem with using an in line LP gauge attached to the tank and having it filled through the gauge. That way, the person filling it (and me) would have a better idea if the tank was really filled. I would have to attach and remove the gauge every time I filled the tank, but that is not much of an issue.

I appreciate your response.

The person filling it doesn’t need a gauge...
They fill it until it reaches the relief valve they opened.
The tanks only get filled to 80%.

Thank you.

Isn't the simple solution to fill the tank, and adjust/calibrate the gauge(s) to show it is either 80% or full (depending on what you want to call "full."

If the gauges are not adjustable, the reading on a "full" tank will tell you which gauge is most reliable.

[Although, if the gauge doesn't respond linearly, it may not be accurate at other levels. A gauge which is accurately reporting a 3/4 full tank may be out to lunch when it thinks the tank is 1/4 full. Gasoline gauges are much better these days, but I can remember when hardly anybody relied on fuel gauges. In fact, my '07 BMW R1200 RT would tell you when it was full and when it was pretty close to empty, but in between it was unreliable. We relied on trip mileage, not the gauge. The discussion boards reported a wide variation in the reliability of the gauge from bike to bike.]
