fresh water sensors

I found the problem. Mice had chewed all but 1 wire to the fresh water tank. I had to remove the inside wall of the storage area to get to the tank and sensors. I put spade lugs on the dressed up wire and reconnected. Luckily there was enough wire on the old connection so I could tel what color wire went to what sensor. Haven't put water back in the tank yet but am confident that all will be right. FYI, at the monitor, if you short the fresh water wire(blue) to ground, and then press the fresh water button, the monitor should read full. Thanks for all the input. It really helped a lot.....
