First, remove the wire from the bottom sensor on the freshwater tank. that is the wire that all the other wires connect to through the water to provide a resistance value for the circuit board.

You can check for continuity between that wire (after it's removed) and the frame or any known ground source. If it is a good ground then touch that good ground wire to each of the other wires(they can stay connected) and you should be able to illuminate each of the different levels. You will need to hold the test button down while you touch each sensor with the ground.
