Fresh Water Always Reads Full

same old story. my fresh water monitor always reads full. i cut the ground wire at the tank and connected to chassis and it still reads full so i assume its not a ground wire. all my wires connect to each other with the black gray and fresh running in line to the monitor i guess. i had the panel replaced and it still did it. soooo, anyone have any ideas on what to do etc? thank you.

    Maybe the tank needs cleaning. Some vinegar in the water, go down the road, drain, rinse. Might work.

    most those gauges don,t work or are not right in the reading. the sensors inside the tank get oxidized .there is a company who makes good one,s some body will chime in with the name ,or rv tank sensors.

    Our RV has a tap on the back of the freshwater tank for draining. I attached a three foot length of clear tubing to the tap and led it up and over something under the floor. When I open the tap, I can see the water level in the tube. It doesn't have to be electronic to work - and it may work better than electronics.
