Manteniment
To ensure the longevity and optimal performance of your wiring harness, consider the following maintenance tips:
- Inspecció periòdica: Periodically check all wiring connections for corrosion, fraying, or loose terminals. Tighten any loose connections.
- Comprovació de fusibles: The harness includes an in-line blade fuse for circuit protection. If your light bar stops working, check the fuse first. Replace it with a fuse of the same amperage (40A, or 10A/15A if you've replaced it with a lower rating for specific applications).
- Neteja: Keep the relay and fuse holder free from dirt and moisture. The fuse holder is water-resistant.

Resolució de problemes
If you encounter issues with your Nilight wiring harness, refer to the following common solutions:
- La barra de llums no s'encén:
- Check battery connections: Ensure the red and black wires are securely attached to the correct battery terminals.
- Inspect the fuse: Verify the in-line blade fuse is not blown. Replace if necessary.
- Check switch connection: Ensure the switch is properly connected and functioning.
- Verify light bar connection: Confirm the light bar(s) are securely plugged into the harness connectors.
- Potència intermitent:
- Check for loose connections at the battery, relay, switch, and light bar.
- Inspect wiring for any damage or frayed sections.
- Light Bar Stays On (even with switch off):
- This is highly unlikely with a properly functioning relay. Re-check all wiring according to the diagram. Ensure the relay is correctly installed.
Note: Some users prefer to wire the switch to an ignition-switched power source to prevent accidental battery drain when the vehicle is off. This requires advanced electrical knowledge and may involve using a fuse tap on an appropriate fuse in your vehicle's fuse box. Consult your vehicle's manual or a professional for such modifications.
