2006 Attitude Toy hauler. JRV micro monitor. Twin 60 gallon fresh tanks. Fresh was full after 2 days tank reads 1/3. Then empty later in day. Still plenty water left. Connection hose clean and free of debris.
Wth?

Empty tanks at home and black reads 1/3 while empty. No biggie. So I pulled the leads on the 1/3 and 2/3 probes. Nothing touching and it reads 1/3. Wth. Ground 2/3 lead and its correct along with full lead.
Is it the monitor or maybe a skinned 1/3 wire grounding itself?

Factory sensors never work. Quit worrying about them.

Sounds like either a bad monitor or damaged cable. Disconnect or cut the wire at the monitor. Some are a plug in connector. Pulling it off will isolate problem to monitor or cable.
Previous poster is correct that the sensors themselves get dirty and will not indicate correctly. By disconnecting as you did proves that is not your problem.

Welcome to the forum! [emoticon][emoticon]

You will find that the sensors are as inaccurate as the latest news on Facebook.

The very high percentage of people on the forum here report the same thing.

My sensors and panel are so inaccurate that I don't pay attention to it. I don't even push the button to check them.

I developed my own way of doing it:

My Black tank sensor: open the flush valve, look down the hole - if it is creeping up to the neck of the pipe, time to empty.

My Grey tank sensor: if I am ankle deep in grey water in the shower, time to empty.

My fresh water sensor: if my water pump is clicking fast and furious, I'm out of water, time to refill it.

After a while you get to know how long you can go with each tank.
My last TT had the fresh water tank under the jackknife sofa. That was easy, I modded the front panel so it would pull away and hinge down so I could just look through the tank and see the level.

The weird thing is i got the wires exposed back to where they turn into one.

I like you style, only issue is I'm always dry camping around 20-30 miles in on dirt. I'm dump the gray when needed but naww on the black. Lol worse part is the fresh tanks are black so I have no visual. Lol

The conductors could be corroded where they exist the cable sheath on either end. That is why you need to disconnect at the monitor panel to see whether it is in the cable or monitor.

Dry camping = be very conservative on usage. Navy shower, if you must shower. Minimal water to flush, wash dishes or yourself etc. Paper plates and disposable cutlery, stuff like that.

When I dry camp I carry 2 big extra water jugs to pour in to the fresh tank.
I can go a week dry camping, but I am extremely careful with water consumption. Showers really kill the water fast.

Well. I'm sorry to tell you that is not "Unsuual" at all. In fact it's quite normal... The "Sensor" well closest thing to it is a nail or screw driven through the tank wall wire connected outside. I'm not kidding that's all it is. and if it's Moist/Wet it figures that tank is at least that full. Slime can do that.
