In my many campers and trailers, I have had problems with the grey and black tank gauges being unreliable. Now I have a new one. My fresh water gauge says that the tank is full even when I dump the tank. There is no paper there to foul up that function. Anyone have any good ideas? I have no ideas, and I would like to have that gauge be a little close. Thanks.

Check the wiring.....tank to interior gauge.

Maybe when your rig was built a 'technician' accidentally piped the black tank and fresh water tank together and it is a piece of toilet paper on the sensor? [emoticon]

If your fresh eater has a lot of minerals in it they can coat the tank walls. Most of the malfunctions on any of the tanks is not toilet paper, it is a coating of scum on the tank walls causing an electrical path between the probes.

Thanks for the answers. Looked at the wiring in the gauge, but haven't been able to get to the wires at the tank yet. Will when I can move it to a better area. The water is hard here, never had problems before, but I guess there can always be a first time. Any idea how to dissolve it and still be able to drink it after flushing? Thanks again.

You might want to use a considerable amount of vinegar, google its use for many different ideas on how to use it.

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. If your board still shows full with that wire removed, then either the board is bad or the wires are connected out of order.

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.

This may be worth a try, hit the Dollar store and grab all of their vinegar. Thanks

I will have to move my trailer up to a smooth, dry spot, (raining now) and work on this. It gives me a place to start. I guess I can add up the amount in the grey and black gauge to guess on the amount used. Thanks for the comeback. Sounds good.

Because we spent 6 months every year since 2001 in the very bad Arizona water I would buy 6 gallons of vinegar at costco and fill the water tank using another 6 gallons of water . Turned the pump on and when the water arrived at the faucet I would turn off and do the same to others. Let it soak for a few days and drain and flush. chevman
