Hi, Thanks for the post. I checked my salt level it is at 3600ppm. I removed and inspected the cell appears to be free of scaling and the outer blades appear ok. I power down the unit and removed and tested the fuse continuity. The fuse tested ok so I put everything back together. When I turned everything back on it started working again. The cell was at 27 volts and 4.7 amps. The next day when I looked it was back at 29 volts and .2 amps. I guess the cell is just dead. I will give autopilot a call today and see about getting a new cell. Thanks again for your help.
