Holding tank sensors not reading

2004 Knight 38PPD

Another issue, my fresh, grey and black tanks do not report status other than empty. I filled the fresh and the black tanks and they both still report empty on the panel.

I've heard of sensors sticking at full when empty, im getting empty readings at full.

Do you have the Aladdin system ? Mine were not working and someone had buggered up the calibration. Once I re calibrated it, it works fine.

My Exec has sensors attached to outside of fresh holding tank, sensors were attached to copper pads, can't remember if others are the same, mine quit reading when a few fell off, I was able to solder them back to copper and all started working. Good Luck

If you have an Aladdin system then you need to replace the sensors. Follow the RJ11 telephone cord to find the sensor.
