Fresh Water Tank Overflow

[BenC]

Vantare does not use the tank monitor model that controls pump or fresh fill. The unit is strictly for tank level indicating and is located in the upstairs MDP cabinet. There is a float switch near the top of the fresh water tank that shuts off the auto-fill valve circuit. Also, to calibrate the Headhunter units, the adjustments are on the back of the display, not on the sending unit located on the side of the tanks. Hope this helps.

Thanks guys. I`ve got it on the operating table now and the doctor should know the verdict today. I`ll report back with diagnosis & fix.

Ben - the tank monitors on our 96 Vantare have not worked since we bought the coach. The tank level display is located on the main electrical switch panel between the galley and the bathroom. The level indicator scale is lit (red) all the way up all the time regardless of how full/empty the tanks are. Is there anything that can be reset to make the monitors work again? Where/what is the upstairs MDP cabinet where the tank level unit is located? Would I know it by another name/description maybe?

Big DUH! I think I may have answered my own stupid question! Could it be that MDP stands for "Main Distribution Panel" and be the same thing as the "main electical switch panel' that I allude to above?

Sorry, I am on Rick's login, but this is Ben. In Vantare lingo, MDP=Main Distribution Panel, which is the main electrical panel area always at the end of the Galley on Vantare coaches. There is no "reset", but rather, if it always reads FULL, there could be a bad sending unit (the pumping unit on the tank), or bad module in the MDP display unit. The sender in the bay on the output wire gives a 0-5vdc signal (empty to full, respectively), that the display needs calibrated to. To simulate empty, pull the air line off the sender in the bay, and it should read 0vdc, and with tank full, should give a 5vdc signal. Hope that helps narrow down the problem. Also, Headhunter Inc in Ft Lauderdale, FL is always very nice and supportive of there product, and you can buy repair parts directly if you so desire. Feel free to give me a call anytime, as sometimes it takes a while for me to get the time to check in on here. 813-830-8619.

Ben,
you`re right Headhunter is very supportive in that they will sell u the complete unit only for $508/ tank sentry , no repair parts because it`s a sealed unit ! Ouch. All three of mine went south even after trying the recalibration steps ,etc. I`m only replacing the black tank for now with the logic that fresh water will fill as needed and shut off when connected to water supply and i know from usage abt when grey tank needs a dump. Fresh water fill valve was removed, cleaned and nothing, needs replacing also $189.

Yesterday, I opened the MDP and examined the back of the tank monitor display. I didn't see anything to adjust there. What exactly am I looking for? Can you describe what I should be seeing on the back of the display?
