Problem with grey tank sensor display

[David K]

I have a 2002 Winny Ultimate Advantage and on this last trip, the sensor lights on the inside "One Place" panel for the grey tank decided to stop working. The outside display located in the plumbing compartment is still working fine so, it is not a problem with the sensors on the tank. I have not had this problem before and during the first part of this trip it was working fine. The other sensor lights on the "One Place" are working fine; ie, the propane sensor, the black tank and the fresh water tank -- all acting as normal -- it is just the grey water display that shows nothing when the small button is pressed. Any help in what might be the problem would be greatly appreciated. I tend to work on things myself with some guidance and am not afraid of trying to diagnose electrical problems with some guidance. HELP !!!

It's pretty rare but it could possibly be a simple case of a faulty or dead led light, if you have access to the rear of the panel you may be able to use a multimeter to run a continuity test on it to see if thats the problem.

Look in your Manual, the OnePlus is resettable. The Manual tells you what buttons to push to reset it and it will relearn all of its functions. If you don’t have the Manual look online:

I took out the One Place center today and cleaned all the points of connection with an electronic circuit cleaner and then lubed them with di-electric grease. Guess what --- yep --- the sensor light is now working ----- guess some non-visible corrosion had occurred and the connection was not good. Turned out to be an easy fix (YES --for one time) -- thanks for the replies above and hope this might help someone else who might have this problem in the future.
