I dont think my Hayward AquaPlus is generating chlorine. I have a new SWG 15 so it is not that. When the SWG is running it does not always show volts or amps being drawn,  I know if I have it set on say, 50% it will cycleon and off. However even if I have it set on 100% or even super chlorinate, it will run for a few minutes then you will see 0 volts and 0 amps.  Is that normal or what is wrong?
