Aqua Creek F-01TL Test Light Control Box. This is a test light control box. It should be used with your Aqua Creek Pool Lift. Aqua Creek has developed a simple and unique tool to help troubleshoot your electronics. Our “Test Light” is a simple LED light fitted on the end of approximately 8 feet of our standard cord that plugs into your lifts control box where the lifting actuator or the rotation motors typically plug in. The light tests for continuity and quite simply, if it lights up, you have continuity through the control box going to the component you are testing (either the lifting actuator or rotation motor).
