Faulty black water sensor
The black water sensor on my 1998 pace arrow vision reads full even though the tank has just been emptied. Short of replacing the sensor is there anyway to know how full the tank is? Also, would it be...

Basically there is an electrode at the bottom of the tank and 3 more going up the sides. When the water reaches the level of another electrode, it creates a circuit between the electrodes...that circuit is tied to the little lights you see.
Works fine with fresh water tanks but with sewage, scum gets stuck to the walls and wicks up water, so the circuits become semi-permanent.
You can mess around trying clean the walls but really more hassle than it's worth.
- For weekends or a longer trip where you move around, just drain before driving.
- If you will be somewhere for a while with a sewer site, just open the drain for a couple minutes every few days (don't leave it open as it causes other issues).
Only place that would be a bit of an issue is if you are staying for a week or more someplace that doesn't have sewer. Then you either need to use a blueboy or haul the trailer up to the dump station. Given some experience, you should develop a good idea of how long you can go between dumps.
