Tank sensor wiring?

[Reb2973]

I have a new TT I bought this year. On my last trip all my tank sensors are reading full. Even the fresh water tank now reads full and never used it. When I went on previous trip before that the tanks all read empty before I put it up. Is there a wire I can check behind panel that would cause this? Hate to drag it to the dealer if it’s something I could quickly fix myself. Thanks.

That helped out a lot. Shows how to troubleshoot my exact problem. Thank you!

If you don't have a manual, perhaps this one will help.

If you have never used your fresh water tank how did you sanitize your fresh water system?

Ok thanks. I’ll pull the panel in the morning and see if I can find anything.

Sounds like you lost the ground wire on the control panel.
Or rather A ground wire
