AutoPilot SWCG Low Amps Cell 0V 0.6A
My Pool Pilot Digital is broken, again. In the three years that I have had it, I have replaced the display board (failure), the power circuit board (high temps), and the cover (screw post breaking).
Now, I am getting the error "Low Amps - Cell". Testing reveals 0V and 0.6Amps. Per the troubleshooting guide, I inspected the cell for scale and found very little. I cleaned it anyway.
I also test all three fuses - all good. Even though it tested good, I replaced the ceramic fuse just to be sure.
I checked my cable connectors, and cleaned my manifold screen filter.
I doubt that my SC-60 cell is bad, as it's only three years old. I purposely bought the larger cell for my 25,000 gallon pool so that it would last a long time. Three years is not a long time!
My water is 7.4pH, 3200ppm salt, and 87F.
I have a multi-meter, and know how to use it. Are there tests that I can do to narrow my problem down to either the power unit or the cell, and/or diagnose the problem?
