thanks for the reply, and i did try that, i also tried testing the flow switch, i checked the relay to make sure it wasn't cooked on the back side of the board and for voltage at the relay, all checked good except the switch, so i took the flow switch to a pool dealer and they said they didn't think it was the switch because they could not get a reading off mine or the new flow switch they had, they seemed to think the problem was the cell i got from compupool for 300 dollars cheaper than the turbo cell 15 that i could have i got from them, but i went with my gut feeling and i know some of you might think your crazy its a open and close switch and a easy check, but when you take it to a dealer and they couldn't even get a reading off a new switch what other choice did i have but my gut LOL, so i got a new switch installed it and bam flashing no flow light for 15 seconds with controller off, no flow light went off, turned it to auto no flow light stayed off and generating light came on and the cell is producing chlorine. last thing i would like to add is even though you can't see a cut in the flow switch line and even though you have it plugged in to the control board which is the basic trouble shooting aqua rite gives you, and a dealer says they can't get a reading off of it or even there new one, that doesn't mean there is not a problem with the flow switch.
