Tank Monitor problem-gctid811002

[knuckledragger]

My readings on my tank monitor are no longer changing. All three readings show the same level even though the levels are changing. For example tank one and two (fresh water) tanks won't move even when adding and using water. The black water tank also stays exactly the same level. Any advice on how to fix greatly appreciated! This is on a 06 490.

More input please. What monitor, how is it wired, etc.

Matrix tank monitors with WEMA senders.

Its odd that all 3 senders would crap out on you all at the same time. Do they all come off the same hot lead, ground? If It were me I would get out the 12 volt tester. Does the monitor light up when you push the button?

Yes it lights up and I did put a 12 volt tester on the black water and it showed it had power. Now to make it even stranger the black water levels are starting to dance around. Went from 24 to 44 percent in about 10 minutes without the toilets ever actually being used. I called the factory and he suggested I remove the sender and clean it. Really hoping there is another option...

Once I began reading your last post I was also thinking pull and clean. Personally I don't know if a WEMA is the right fit for a poop tank. Lots of nasty stuff can get stuck in between the doughnut and the shaft but cleaning it would definitely help. At least that one shows some life. I'd pull all 3 of them and exercise them while someone is watching the monitor. It requires a little work but not all that difficult.

Also test the wires on the fresh water tanks.

Actually I think you are right on! After using the boat I see the black water monitor has come back to life so cleaning may be the fix. Thank you for the help!
