Optic Lighting YMS-TY01 main box light not working how to troubleshoot

[McAniyah]

If the main box light on your Optic Lighting YMS-TY01 Universal Ambient Light isn't illuminating after installation, here's a troubleshooting guide to help you. First, consider these potential causes: The power supply connection might be incorrect, the grounding may be inadequate, or the lamp head could be unplugged or damaged. Here’s what to do: Ensure the power supply line is correctly connected to a 12V power source. Verify there is 12V (between 9~16V) between PIN1 (GND) and PIN2 (power) using a multimeter. If the grounding is suspect, switch to wiring grounding. Finally, check that the lamp head connector is securely plugged in, and if the light still doesn’t work, the lamp may need replacing.
