Electric indicator Panel

[Joan D'Andrea]

Has anyone taken their panel apart. Mine blinks like a neon sign in a storm. Sometimes it's on and sometime's it's not. One minute it says I have 3/4 a tank of fresh water and the next time I have a half tank and then back. The only way to keep the pump button shining is to wedge a toothpick in between the case and the light. I have been hesitant to look inside,but this is gettin rediculous. JLD

That sounds like a loose, open or shorted wire.
On a different but related note, you can calibrate your holding tank gauges on many models with a small screwdriver. Look for small holes on the face of the panel under the gauges and you should see set screws deep in those holes. Fill the tanks full and turn the screw until it reads exactly full. I know my 76 had this but not positive on the 78. Check the owners manual.
