I am trying to determine if my cell is bad or my AQL-P-4 board is bad. My local pool store has tested my cell, which is 10 years old, and says it is generating chlorine (cost me $50 for the test!). The errors I get on the board say 'Check system no cell power' and 'Chlor off test salt level'. I tested the water at the pool store for salt and I used a test strip (Aquacheck test strips) and it read 3200ppm and the water temp is 62F, so the cell should start based on Goldlines manual. A few years ago I had to solder the board for the cell power issue. Any suggestions on how I can figure out which one needs replacing? Thanks.
