Hi,
I just replaced the control panel/display on my Hayward PL-4 Aqua-Logic system. Everything works fine (filter, heater) except for the AUX1 (vacuum) and AUX2 (spa jets). I hear a clicking sound when I press the buttons on the keypad (which leads me to believe that the relays are working), but neither motor turns on.
Any help would be greatly appreciated.
