Thanks James appreciate your help here. Yes it seems it is producing but how much is the question - the pool is blue and looking pretty good so it's enough for now. I'll test it & know for sure when the sacred TF-100 arrives (lol). These summer conditions here now are intense - left the cell off yesterday as I added salt so it could dissolve, and the pool started going slightly green already. But I added that liquid chlorine to 10ppm today as ping recommended so it'll be good tomorrow. Be good to accurately test CYA also (around 40 atm according top pool shop) then optimise it to the right level.
Re the DC current, the person from Crystal Clear who sounded fairly technical said it was a half wave rectified, not smoothed signal so he felt it would get a reading on an AC clamp meter. Would you have tried measuring this type of source using an AC amps clamp to see how close it is? Assuming the missing negative swing is ignored, then the clamp meter should read approx the current at the half rectified peaks shouldn't it? Today it was reading 16.5A, but the reading is very consistent.
Re the transformer interference, so it could provide harmonics etc. that threw it off? To me it just seems the 14/16A sounds about right given 30A rated when new.
Prob fighting a losing battle with this but still really interesting to think it all through.
