I have an 89 Excella that is close to being near perfect. The only problem that I cannot solve is the sensor panel in the range hood that indicates battery, grey, black, and fresh water levels. It reads the battery level just fine; but when checking the other levels the indicator reads empty no matter what the true level is. If you hold your tongue just right it will just for an instant scan full or perhaps even true.

I researched on here several months ago and a fella was trying to get a line on someone to repair this. The part is unobtainable from the factory, In Land Marine, other dealers, used parts, and other salvage places.

I took the panel off yesterday and it is manufactured by Larson Electronics Mfg, in Fullerton, Ca. Many hours of research found the company who bought them out back in the mid 90's. A tech there informed me that they had no way to repair them and the one guy who used to do this is now overseas.

The electronics is old style transistor, resistor, diodes, capacitors, etc.........Calling to find someone who could troubleshoot these old devices in the Atlanta area has found no one...........I find this really hard to believe. Even someone who could take the little board and directly replace the components without testing them.............

So, yes, I can look down into the tank of the black water from the toilet and judge from that when it needs to be dumped. The grey water, when it begins to back up into the shower needs taking care of. It's the fresh water that has me stumped as to get a reading on. I hate to drag around all of that weight or even worse not to be able to plan booney water replacement needs.

Yes, as the really nice parts lady at Inland suggested I can put a new sensor system in; but I just finished up redoing the bottom skin and really do hate pulling that, the tanks, etc to put in new probes................

What to do?............thanks guys...........Dennis
