'87 Westy Syncro--water tank level indicator uses the
conductive plugs into the tank.

It has worked fine--except for the "yellow goes to red
pretty quickly" problem--until recently.

Now it shows a full tank--green--all the time, even
when the tank is empty.  I suspected a connection to one
of the plugs, since I was messing in that secret compartment
but I checked and they all seem OK.  So now I suspect some
problem in the circuit of the LED panel.

Any ideas or experience or knowledge?  David?  ;-)
