4.2 Wiring Instructions

The switch panel comes pre-wired for convenience. Connect the main positive (red) and negative (black) wires from the panel to your battery. Then, connect the positive wire of your accessory (e.g., LED light) to Pin #3 of the corresponding switch. The negative wire of your accessory should be connected to the battery negative.

Wiring Method A: Constant Lower Light

In this method, the lower light on the switch will remain constantly illuminated when the panel is powered on or the vehicle's key is turned to the ON position. This provides continuous visibility of the switch location.

Wiring Method B: Lower Light On with Accessory

If the wire connected to Pin #6 (typically the lower light power) is disconnected, the lower light on the switch will only illuminate when the switch is activated (i.e., the accessory is turned on). This conserves power and indicates active accessories.

5. Operation

Once installed, operating the Nilight 90116C switch panel is straightforward:

• Rocker Switches: Press the top part of a rocker switch to turn on the connected accessory, and the bottom part to turn it off. The upper LED indicator on the switch illuminates when the accessory is active.
• Dual USB Charger: Plug your USB-powered devices into either of the two USB ports for charging. The charger provides a total of 4.8A (2.4A per port) for efficient charging.
• Voltmeter: The digital display on the USB charger continuously shows the current voltage of your vehicle's electrical system, allowing you to monitor battery health.

6. Maintenance

To ensure the longevity and optimal performance of your Nilight 90116C switch panel, follow these general maintenance guidelines:

• Regular Cleaning: Wipe the panel surface with a soft, damp cloth to remove dust and grime. Avoid abrasive cleaners or solvents that could damage the finish or labels.
• Inspect Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to intermittent operation or electrical issues.
• Waterproof Integrity: While the panel is waterproof, ensure the USB port cover is properly closed when not in use, especially in wet environments, to protect the internal components.
• Switch Functionality: Test each switch periodically to confirm proper operation. If a switch becomes stiff or unresponsive, inspect for debris or damage.

7. Troubleshooting

If you encounter issues with your Nilight 90116C switch panel, consider the following troubleshooting steps:

• No Power to Panel/Voltmeter Off:
  • Check the main positive and negative power connections to the battery. Ensure they are secure and free from corrosion.
  • Verify that the vehicle's power supply (battery) is functioning correctly and providing adequate voltage (12V-24V DC).
• Accessory Not Turning On:
  • Confirm that the accessory itself is properly connected and functional. Test it directly if possible.
  • Check the connection from the switch's Pin #3 to the accessory's positive wire.
  • Ensure the switch is fully engaged in the 'ON' position.
• USB Charger Not Working:
  • Verify that the panel has power (voltmeter is active).
  • Try a different USB cable and device to rule out issues with your charging accessories.
• Lower Switch Light Always On (even when accessory is off):
  • This is typically due to Wiring Method A (see Section 4.2). If you prefer the lower light to only illuminate when the accessory is on, ensure the wire to Pin #6 of the switch is disconnected (Wiring Method B).
• Voltmeter Display Inaccurate:
  • Ensure stable power supply. Fluctuations in vehicle voltage can cause readings to vary.
  • If consistently inaccurate, contact customer support for further assistance.
