So for some reason this year the output lights were not coming on when the timer restarts the pump and chlorinator every morning. I found an old thread on this site that reminded me of the " hidden reset button" that is just and inch or two below the Output Button on the chlorinator. You can feel a slightly raised surface here. Hold the button for 5 seconds you willl hear a click and the output light flashes. This fixed the problem. I have now joined this site and wanted to relay this info. Ottawa, Canada
