I put a new salt cell (Generic T-15) on my AquaPlus system. I'm getting "Chlorinator Off, No Cell Power" and "Check System, Cell Power 1" error messages. Read pretty much all the stuff here and elsewhere. Replaced the GLX-PCB-Pro mainboard with a new one. Changed the 20A fuse to 15A before starting up. Replaced Rectifiers. Transformer voltages seem fine. None of the mainboards appeared to have scorch marks or cold solder joints. I got the last new board to run for about 4 days and things seem fine. Now that board is giving me the errors. I also tried my old salt cell without luck.
I can't think of anything else at this point. I'm considering returning the mainboard and salt cell and trying yet again but I'm starting to have my doubts whether something else is going on. Any ideas?
