I have a 2009 AquaRite  salt water generator -  40,000 gal. I recently replaced a TCell 15 with a TCell940SWP -  It seems like it is not producing much chlorine.  Salt level is 3600 which I will dilute.  Ive been getting odd displays - (all lights lit, no superchlorinator light, otherwise the readings are in normal range 24.1, 6.77.  I tried calling Hayward and gave up after an hour on hold.  Should I change out either or both of the circuit boards.  Can I upgrade the boards.  Since I just bought the cell, Im not up for buyng the whole kit.  Thanks,  David
