Poolsean,

thank you very much for the reply. Ok, I took the cover off and, no loose wires. What I found was.....

1) the Cell cord wires (red/blk) at the banana clips were twisted at the insulating boot and had grounded....I separated the wires and taped but that did nothing.

2) the board at the bottom has 6 resistors... R25 R19 R27 R23 R22 R20...

R25 and R19 had some corrosion where soldered.

Do you think it could be a bad Cell cord? or the board?

as I previously said, there are no codes, just can't make chlor. or adjust the salt level, everything else seems to be functioning properly.

again thank you so much for the reply and info.
