Black/Grey water guages swapped


This Spring, I purchased a 2013 Surveyor Sport (295) that appears to have been built on a Monday...

My 'information center' in the bathrooom has buttons to show the level of black water, grey water, fresh water, and the battery charge. What I've discovered is that when the black water shows full, it's really telling me that the grey water is full (and vice versa).

The dealer thought I was imagining it when I told him. So, I paid more attention and when I've got the black water button showing full and the grey water showing 1/2 full, I can pull the grey water handle, leave it open for 5-10 min and then close it. I retry the black water button and it shows empty while the grey water button still shows 1/2 full. So, to me, that says someone wired them backwards to the information center. Dealer still doesn't seem to want to deal with it (maybe because it's parked at a permanent site 60 miles from the dealer and he doesn't want to travel that far to fix it).

The information center has 5 wires connecting to the back (4 guages plus ground, I'm assuming). Does anyone know which color wire is connected to which tank in a correct configuration? It looks like I could take 2 wires out of the connector and swap them if I can figure out which is which. Since there's only the 5 wires, I could use a trial and error method and just start swapping wires until I get it right but I'd rather minimize the time I spend fixing a new camper and maximize the time I'm enjoying it.

Any help would be appreciated.

Well being you are 60 miles-------------

Being you are 60 miles from your dealer, you might have to bite the bullet and use trial and error by disconnecting one wire at a time until you find
what wire goes to the black tank. Then do like wise until you find the gray tank wire. Then, it will be a simple process of enjoying your time after you have corrected the problem by switching the two wires.

Thank you.


Thanks. Won't be at the camper until this Friday. If no one else has the information, I'll go that route and document what I find here when I get back from the camper in case anyone else runs into a similar issue.

I wouldn't rely on your gauges to be even remotely correct even if there marked correctly.
On my old tt the black tank revealed 2/3 full when empty then the next time showed empty when empty.
I piece of toilet paper on a sensor will throw a wrench in it all.
That being said its possible that there switched but my money is inaccurate readings.

Try the (geo-method) on keeping tanks clean that's my opinion.

Drain gray water then fill with hose and watch readings?

Also, wouldn't it be simpler to simply change the labels on the switches?

Edit note: Just saw that Goodneelix already said this.

Wouldn't it be easier to apply new labels to the sensor display box instead of trying to swap out wires? There are good label makers on the market that make nice looking labels that don't look cheesy.

A label maker can come in handy for labeling all kinds of things including powercord chargers that tend to look alike but aren't the same.

I do have a rather nice p-touch label maker and thought about doing that to the switches. The issue I (well, my wife ) have with that is an aesthetic one. When I think about modifications to the camper, I'm thinking in terms of mods that improve its usefulness or aesthetics vs trying to hide something done wrong at the factory.

The wiring on the back of the switches looks pretty simple to rework (pair of needle nose pliers to pull the wire out and a small flat screwdriver to push it back in) so I figured I could leave the 'original beauty' of the 4-button panel and just swap a couple of wires (once I figure out which wire is for which button).

I do appreciate the suggestion though. I may just need to bring mine along this weekend when I swap the wires so that I can label the wires before pushing them back into the wall behind the panel.

How about switch the pull handle labels?

I'm a little confused by your suggestion. Are you referring to the handles that open up the tanks to drain? If so, they're technically not labeled. They are, however, color coded on my Surveyor. My grey tank has a grey handle and my black tank has a black handle. A simple little thing but it does tend to help make it 'foolproof' for someone new to camping in a 'hard-side' (my previous camper was a pop-up without a bathroom).

f1100turbo (Ron),

The dealer warned me that the sensors in the black water tank could catch debris and show the tank fuller than reality. My Surveyor came with a 'rinse-out' connection to the black water. To the right of the outdoor kitchen on my camper is a water connection. This connection goes right into the black water tank (there's some form of sprayer built into the tank to wash down the sides).

My dealer highly suggested that whenever I drain the black tank, I hook up a garden hose to this water connection and run water through for ~5 min to rinse the sides of the tank down to minimize the chance of something being hung up on a sensor. A useful feature on this model.

There is not a similar feature for the grey water (although, I wouldn't expect a need for one either). But, the dealer did point out that, much like when you cook pasta in a pot a home, a thin film could build up on the inside of the grey tank from the soap from the shower and kitchen sink. He suggested cutting open one of the packets used for the black tank and carefully pouring it down a drain to the grey tank to try to minimize the 'scum' buildup.

I will search the forums for the geo-method to see what that is and how it works. Thank you very much for the suggestion.
