gray water sensor dead
RE: 2006 Safari 25' FB
After 6 years of use, suddenly the gray water sensor light on the control panel is blank. When I boot up the control panel, all the correct lights flash opposite the gray tank marker. Yet, when boot up is complete, there is no indication color whatsoever for the gray tank.
So I guess I have some sort of electrical problem. I'd love to hear from someone about the logical steps necessary to diagnose this problem and repair it myself, if possible. As a beginning point, it would seem that the control panel itself is working because it flashes all the normal colors during boot up. So when there is no color at full boot up, doesn't that mean that I'm not getting any kind of signal? So the problem is somewhere from the point at which the wire(s) hook up to the panel out to the sensor itself?
Frankly, I looked underneath my trailer and I couldn't even see a sensor connection point to the gray tank. The instruction manual suggests it should be low on the tank. But maybe what I think is the tank is only some kind of protection cover and the sensor is hidden underneath?
I'd appreciate any comments, fellas!
