I had to remove a fresh water tank to repair a leak. I labeled the wires from the tank sensors but messed up somehow hooking them back up so I have no monitor display. I have white, yellow, orange and green wires. It is easy to see which sensor gives the reading on the tank, does anyone know what color wire goes on each sensor?

Donald, do you know what brand your holding tank monitor is ?

The only thing I see on the monitor is "Custom Design by KIB". The trailer is a 1998 Aljo Sport Wagon toy hauler. I have contacted Skyline but no response yet.

Good morning, Donald; 

Also, most of the motor home body makers (Airstream, Holiday Rambler, Winnebago, Barth, GeorgieBoy, et cetera) could all choose the wiring colors they wanted to use in their coach bodies.  A few of them used one color wire insulation, but they printed numbers on the insulation for indicating the function of that wire.  For those, normally you need their wiring diagrams. 

My goal in saying this is to justify my asking; "What brand and model motor home do you have?" 

Enjoy;

Hi Ralph - the trailer is a 1998 Aljo Sport Wagon, built by Skyline. As I noted in a previous post today the only id I see on the monitor is "Custom Design by KIB". I don't have a wiring diagram for this unit and can't find one on line, probably because of the age of the trailer. I have contacted Skyline but no reply yet.

Hi, This is only a guess, but I don't think you can damage anything by trying.  I would expect the white wire to be the common, and contact between this and any of the others should light the various bulbs.  So, one at a time connect each of the colored wires to the common and record which bulb lights up, then attach in proper sequence.

Thanks for your reply. I did try your suggestion but didn't get any lights. I suspect the liquid in the tank somehow completes the circuit, but that is just a guess.

Yes, the liquid should complete the ground. A site that I looked at suggested that a bad ground (the white wire) is a common problem. They suggested that a jumper wire be used to check the lights. A good ground connection to the vehicle frame, connected to the individual colored wires.  One at a time should show which wire should connect to which probe.  To be safe, it would be a good idea to have a fuse in the jumper wire!

I would use a volt meter or 12 volt test light to be sure of which wire was ground and which had power. After that then you can ground the ones with power to check the lights. At least that way you know if you have power coming out of the control panel.

Use a known good ground for the meter or test light

Hi - I appreciate your answers. I tried the test light. Don't have power to any of the tank hookups, yet the monitor does have power and the grey, black, and battery indicators on the monitor are working.

Then it is a capacitive system and you will need a logic probe or a scope. I am not real familiar on those, I did see a write up on one a while ago. I will try to find it, I save all of that kind of stuff.
