Hello,
I have a Hayward Aqua Logic controller and a T15 salt cell. The cell is about 1-1/2 years old. I tested the salt level and it showed a lower reading than what the pool store showed in their water test. I cleaned the cell and tested again and realized that I was getting substantially different readings for each polarity. The readings are:
-27.39U, -3.70A, 1600 PPM
+26.51U, +5.16A, 2500 PPM

Is the cell bad or is there a problem with the board. I've read different posts on here that talk about the relays or limiter. Thanks for any advice you can provide.
