I have a 2009 310DA with a 28 gal vacuum flush system which the monitor in the electrical panel doesnt read properly. It has a switch to turn it on and when doing so all the indicators light up. They are Empty, 1/4 full, 1/2 full 3/4 full. I pulled the three sepperate floats out of the holding tank and cleaned them. I also did a check with an ohm meter to see if they worked, the short and medium ones pegged the gague when I lifted the floats. The longer one worked the opposite. On this one when I lifted the float the gague went from pegged to zero. I'm guessing that the longer one works differently as to indicate when the tank is empty and lights up that on the monitor. When I put the three gagues back in the monitor still lights up all the levels and the Empty. I want to try and replace the monitor, however cant find it anywhere. Not only that all the three floats I see now are on one unit and not seperate like mine. Any ideas where I can find a monitor and three speperate floats to replace it all with and be done with it.
 
Have you tried flipping the floats? If installed upside down they will stay lit the way you describe.
