Recently replaced a dead Hayward T-15 cell with the one recommended by CircuPool (discountsaltpool.com). After installing the CircuPool cell, it's not generating chlorine. My readings from the Hayward Controller, while running with the 'Power' and 'Generating' lights on, are: Salt-3500, Temp-85,Voltage-26.5, Amperage-7.27, Output-39% and Salinity (-3300) - yes, minus 3300!? Of course, CircuPool (Discount Salt Pools) says I have to contact Hayward or send the cell in for testing, and Hayward says I have to contact the cell manufacturer... frustrating to say the least. Any suggestions before I send the cell back for testing? At this point I'm almost ready to bite the bullet and pay the extra $100 for a Hayward cell.
