Iím getting no chlorine out of my system despite new equipment.

New GLX-PCB-RITE circuit board and new T-15 cell.
All chemicals are balanced within range.
Pool store shows salt love is 2900.
My Readouts are:
> 3300
> 75 degrees
> 26.5 volts
> 6.29 amps
> 80%
> -3300
> AL-1
> r 1.59
> t-15
>
> Ran the system overnight at 80%. Chlorine in
> pool remained zero.
> Ran the system overnight on Superchlorinate.
> Chlorine in pool remained zero and Superchlorinate indicator remained
> lit even after 12 hours.
>
> What am I missing?
Thanks
