I've owned my pool for 5 years now. T-15 cell gave out, replaced it today. On the negative polarity, it's showing 10+ AMPS, and salt level of 2000. Salt tested at 3600. On positive, shows no AMPS, and the Voltage goes to Low Volts. Was hoping that the new cell would finally take care of my problems, but alas no. Also, I on my display, it shows a Communication Error 2. What is that? Any help appreciated! Thanks.
