Holding tank gages
I have a 2k16 Sierra 355re my black gage reads full all the time and my gray & galley tank gages read 1/3 all the time. No matter what level is in the tanks they read the same all the time. Fresh wate...

It basically an unavoidable issue (or at least not worth the hassle to keep them working).
Basically, there are metal electrodes set at different levels in the tanks. The idea is when the fluid level reaches the height of the electrode, the fluid completes a circuit and that is connected to the lights on the readout.
The problem is as crud builds up on the sides of the tank, there is enough moisture that it bridges the gap to the upper sensors completing the circuit even though the tank is not full to that level.
You can spend a lot of time and effort trying to clean them thru various methods with varying degrees of success but the minute you stop the issue will return. Or you can get a rough estimate of how long you can go on tanks and just drain beforehand.
