Well, I contacted Goldline support this afternoon and finally found out my problem.
I purchased the wrong cell for my unit. My old one was a T-Cell-15 and I purchased a GLX-T-Cell 5W - which Goldline said was for a smaller sized pool. Apparently since it was operating on my control unit - which was designed for the larger sized pool - the salinity readings would read out at half of what the actuals were. So the 1800 reading it was getting was actually 3600.
I have contacted the Ebayer to see if I can send this unit back and get the correct one - which is of course $150 higher. If he says no then I guess I will have an "almost new" one listed on Ebay myself. :-D
I guess I should have done some checking but the cells all look alike and the ad read Aqua Rite 20K - which to me meant for a 20,000 gallon pool - which mine is. Apparently that meant is was for an Aqua Rite - 20 model. Not sure why Goldline would have named them that since they were not for 20,000 pools, but oh well.
So this will be a costly lesson when it's all said and done. I do have a new backup control unit now, so if that goes out in the future I'm covered! :-D
Or I may stick that back on Craigslist and see if someone else needs one - assuming I get a new cell and get my old control unit working.
Again, thanks to everyone for the feedback and suggestions. I hope my next post is that I have it working again!
