Tank sensors January 10, 2017, 11:18:05 am I had my 1992 MB for seventeen years and the original sensors all worked fine. I was surprised when I discovered the seniors in our new to us 2004 MB don't function at all! I've read all the advice on in the handbook and looked through the archives. I've tried the various "fixes" suggested for cleaning the tanks but no improvement. We are thinking of going with the Horst sensors because of cost and they seem to be more of a DIY project. We'd like advice on installation. Another question is that the fresh water also reads empty. Horst doesn't even have a replacement. I'm thinking that there must be a connection issue rather than fouled sensors.

They do not plug up, the sensing is done from outside the tank electronically.Many of us have used SeeLevels for 10-15 years.709 SeeLeveL II⢠Tank Monitor System - Garnet InstrumentsAmazon.com: SEE LEVEL 709: AutomotiveIt's a nice upgrade that gives a much more accurate measure of remaining capacity of the fresh, gray, black and propane tanks.Larry 2 Likes As an Amazon Associate Lazy Daze Owners' Group earns from qualifying purchases.
Re: Tank sensors Reply #2 – January 11, 2017, 10:26:36 am To add to Larry's post, when we went from an '83 to an '04, I was struck by the uselessness of gauges that increment in thirds! At least the ones in the old rig read out in quarters, still marginal. The SeeLevel gauges read out in percent, in increments of about 4%. Accuracy is still only as good as the installation accuracy, but you do get a good feel and confidence for what is in the tanks after a little experience.Steve 1 Likes
