SWG mixed messages

[stevenhlee]

autopilot digital SC-36 giving me mixed messages. about 2 weeks ago it read warning clean cell. So I cleaned the cell, now it looks great. then this week it read warning low Amp, pool store recommended new cell cord. So now I have a new cord. Now the message reads again warning clean cell. What gives. Do I need a new cell? Cell about 3 yo. manufactor says this is average.

I am in central florida. It has been a hot June. Readings below.

94 degrees
pH 7.4
FC 3-4
total alk 100 ppm
CYA 80
salt 3500
2 hp pump, 9 hours running time

digital read out says 15V, 4.0 Amp

Test your salt level and compare to the 3500 ppm that the unit is reading. Calibrate the Pool Pilot if needed.

If your cell is worn out, look at the two outer blades to see if they are shorter than the other three blades between them. If so, yes, you will need a new cell.
