False LP Gauge reading

[OnJa]

My LP gauge in my control panel on my Monaco MH reads "full". It even does this when I disconnect it from my LP tank. Is there a 'inline' fuse someplace, or any suggestions?

same issue on my 10 tour... look forward to the response!

I don't think there is a fuse. On my HR Ambassador my black tank indicator it shows full all the time on the inside monitor. I have another monitor outside and it works correctly. I think it may be a failure of the small control board behind the control panel. Just my guess.

Didn't see no control board, only gauges, switches, wires and indicator lights.

Take a look at this thread may help.
When I adjust my pots if water comes into the shower GRAY tank is full.
Other two black tanks, go camping for weekend and use flashlite to monitor when full to floor line that tanks full.
When you fill LP tank adjust knowing its 80% full.
