My new-to-me 2006 H41 as the WEMA tank level indicator system with the analog gauge and the diagram of the little boat and the ability to monitor seven tanks although the boat has four tanks (two fresh, one black and one fuel). I'm not sure if it's hooked up to any other things to monitor. None of the lights on the boat diagram light up and the gauge doesn't move for any of the settings other than for one of the water tanks (I think). I have not looked at any of the sensors to see if the floats are stuck or need cleaning, I still need to do that. Is there a replacement for the display unit that works well with the system without having to remove and replace sensors or wires? I see in some of the threads discussions about external sensors. If they are anything like the sensors that are in my past RVs, my experience with those is that they don't work very well.
