Water Level Sensors?

Yahoo Message Number: 76702
I have a 2000 Allure and two of the water level indicator lights have stopped lighting up. The two that aren't working are the 1/4 and 1/2 level lights. The others work fine. Any suggestions on troubleshooting and repairing?

Thx,
Brian

Pull the panel and see if they are connected. The wiring is pretty thin and they could have vibrated enough to break.

Thx for the input, but the same lights are used for the fresh, black, and grey level readings. The 1/4 & 1/2 level lights work for the black and grey level readings, but not for the fresh water readings.

Any other ideas would be appreciated.

All that is doing is telling you that the lights are good. It does not tell you the wiring to the specific tank is ok.

For what it is worth, I had problems with my sensors reading correctly. Upon checking the tankings, I found the senors where the stick-on kind and some had come loose. I re-glued and ducttaped them back in place and all is now well.

Duh, I got it. So at this point, I know that the lights work, but they are not getting a signal. I need to drop the panel and check the connections between the indicator lights and the fresh water level check switch. I also need to find and check the connections on the fresh water tank.

Thx,

If you dig your schematics out, you will find there is a couple of circuit boards involved. I would pull the inside panel and check the connections and then check the wiring at the tank sensors. You might want to do a continuity check between the board up front and the tank.

I cannot help you with your specific coach, but I had to document the wiring for the tank monitoring system to repair my automatic water fill pcb.
From the wiring number list furnished by CC, I learned that the tank level probe wire for each level run to a Tank Monitor PC Board. One wire seems to service all four tanks.
It also appears that each tank has one wire that runs to the Tank Monitor Board.
The message received from a combo of two wires tells the Tank Monitor Board to light up an LED on the level indicator.
If I am correct (always subject to question) the problem you have may be on the Tank Monitor Board and not in the wiring?
I had to locate all the wire numbers for tank monitoring on the provided CC list and then draw a diagram of their "from" "to" origin and destination to try to make sense of the system. There was no diagram of the overhead console wiring in my manuals.

Perhaps that will help you locate the specific problem also.
