Tank Sensors - Recently bought a previously owned Bounder 34J and the Black Waste Tank sensors are not working. They show FULL when the tank is empty. I'll try the Gauge Level Cleaner next time I move it to see if that will correct the problem. MEANWHILE, however is there a way to get the tank sensors to work other than internally with the cleaner? Do they generate voltage which can be measured? Any suggestions? Note the Black tank is not translucent (like the other two) so you can't see into it to determine level. Thanks.
Sooner or later everyone just gives up on the sensors and finds their own method. Some are great at estimating; some use the flashlight; some find other creative (or not so creative) ways. One person I know says that when the water begins to back up into the shower, then she knows the grey water tank is full. Not the best method, but works for her. Obviously this wouldn't be the ideal solution for the black water tank.

Ventline who makes most of the monitor panels has a booklet on troubleshooting. The panel has potentiometers,pots, that allow the sensitivity to be adjusted. There is one pot for each tank. You will need the model number and you can call the technical support people at 219-848-4491. The addition of an intank flusher will help the tank stay clean and the monitor read correctly.
Yes, with a voltmeter you can check the sensors on the tank. On the side you will note wires attached to the 3-4 "sensors". The lowest one on the tank should have 12 volts dc, use the frame as ground. As fluid level in the tank rises an electrical connection is made as the fluid covers the other sensors. The "sensors" are simply a metal stud that protrudes into the tank.
Check the other sensors, if the tank is empty there should be no voltage on the other sensors. If a sensor has dc voltage and the tank is empty you have material in the tank that must be removed. The above posts apply!
If the tank is filling and not turning on the lights on the monitor you may have a poor connection. If the tank is full you should have voltage on all the sensor connections. If the sensors have voltage and the panel light(s) are not turning on note which lights are not on. The tank sensors correspond to the tank sensors bottom to top. Check the wire connection for the sensor(s), the connection may be loose or corroded. If the tank is full and no lights are on it may be bottom connection that supplies the 12 volts dc, check it.
If the tank is full and the sensors have voltage and you still have missing light(s), the problem is most likely to be a broken wire from the tank sensors to the monitor panel. Last it may be the monitor panel or a connection on the monitor panel.
Like most everyone else I finally gave up. If it's just me and my wife we can usually last 4 - 5 days and then we dump. I have tried everything and most remedies will last for a while. The best was the ice trick. Put some cleaner in the tank anf fill the tank 2/3 full of water, if you can tell, and then dump in a couple sacks crushed ice. Drive around for 10 - 15 miles, up and down some hills, around corners and curves, etc. to shake up the ice. This should clean off the sensors and will work for a while. If this doesn't work then you probably have some other problem and I have no advise other than to pull everything and that could be a mess. Not worth it in my opinion. I just got used to it.

My worst day camping was better than the best day I ever had working.
My problem has always been the grey water tank. I used about 3 gallons of windshield cleaner (like 20/20) in a 1/4 - 1/3 full tank and found it worked well. Took a couple of treatments if i recall. My rig is 14 years old and the sensors work fine. Now, if I could just get the tanks to hold more [grin].

I happened to notice that Alpenlite is now using some sort of emitting, non-submerged sensor in their new 5th wheel tanks. That is all I know. Anyone else up on this? Is there a retrofit possibility here?
I too am one of those who has given up on the waste tank sensors.
