Aquarite system; t15 cell; 20k gal pool; 3300ppm salt; 1.5 total chlorine; 0 free chlorine; I added the recommended chemicals (conditioner) and ran system on super chlorinate for 24 hrs as recommended by pool store... after 24 hrs, noticed that neither power nor generating nor super chlorinate lights were on. they will intermittently appear (light up)...i can't isolate the conditions that make them light up. little black disc (mentioned below) looks "ok". when lights are off...diagnostics show low volts and 0 amps. once or twice, the generating light came on with no power light. now no lights on again...uggsss. I don't trust the pool stores...i fear they don't have a true expert who can diagnose the problem, rather i suspect they try and sell me a new board or system (or maybe just more chemicals!). Is this sympomatic of a bad current limiter?
