348.6F Hot Tub Light Will Not Come On (J200 Collection CL Lighting)Diagnostic Tools: VoltmeterSuggested Spare Parts: Circuit board, DCU, LightsStandard Troubleshooting Approach (Light has a two hour time out)All the LEDs are controlled by a central control box (protected by a inline fuse), the topside control panel func-tions and color cycles. The LED cables are daisy chained together with locking Molex connectors, they are runclockwise, starting at the front right corner of the spa.One or two LEDsare out.Many LEDs areoff.LEDs are out ofsync.None of the LEDsturn on.All LEDs turnon but one colordoesn’t light.Remove cabinetwhere problemLEDs are located.Remove cabinetwhere the firstLED daisy chainis located. LEDsrun clockwise, startpoint is at the frontright corner of thespa.Remove cabinetwhere the firstLED daisy chainis located. LEDsrun clockwise, startpoint is at the frontright corner of thespa.Check voltageacross points 18and 19.Disconnect thecables one at atime starting at theopen end of thedaisy chain.Check the daisychain connectionfor the lightharness.Check the daisychain connectionfor the lightharness.Check lightcontroller fuse.Located on the redpower wire of thecontroller.Check LEDs afterdisconnecting eachcable.Replace bad LEDswith a new daisychain cable.Replace with a newdaisy chain cable.Continue to thenext daisy chaincable.Replace with a newdaisy chain cable.Continue to thenext daisy chaincable.Plug new daisychain into lightcontroller todetermine if it isthe controller or anLED cable issue.If LEDs start towork properly,then the last cableremoved needs tobe replaced.Check the daisychain connectionfor the lightharness.
