Black Water Tank Gage
My black water tank gage always shows 2/3 or full even though I've emptied it and flushed it. What would cause this gage to not read accurately? and how can I fix it? thank you

Our RV has sensors that stick on the outside of the fresh, grey and black tanks. These are proximity sensors and I would guess that they work in a similar way as a stud finder finds studs in a wall. This arrangement works great. The Black Tank circuit on the main board in the control panel went out, but fortunately the toilet sits directly over the holding tank so I keep a flashlight handy. Swapping sensor leads proved the problem to be in the control panel. Great system, only if it lasts longer than the warranty.
