I have a pool pilot digital system i got with the pool in my house i just bought. I have put about 9 bags of salt in the pool, it is a 12,000gal. That should have it to around 3200ppm. The system is now saying Low Amps-Cell? I had around 9 volts, 1 amp, and after i cleaned the cell i get around 16 volts 1.1amp. Any ideas what is going wrong?
