- Rubber Seals: Ensure the rubber seal caps for the USB and 12V sockets are properly seated when not in use to maintain waterproof integrity.
6. Troubleshooting
If you encounter issues with your Nilight 90107D switch panel, refer to the following common troubleshooting steps:
- Device Not Turning On:
- Check the switch position. Ensure it is fully engaged in the ON position.
- Verify the power source. Ensure the battery connections (red and black wires) are secure and the battery has sufficient charge.
- Inspect the fuses. Check the two 15A fuses on the panel's wiring. Replace if blown.
- Confirm device wiring. Ensure the positive wire of your device is correctly connected to Pin#3 of the switch and the negative wire to battery negative.
- USB Charger or 12V Socket Not Working:
- Check the main power connection to the panel.
- Ensure the device being charged is compatible with the output voltage/current.
- Verify the integrity of the charging cable or device plug.
- Lower Light on Switch Not Illuminating:
- The lower light on the switch is designed to be constantly on when the blue wire is connected to the battery positive (+). This helps locate the switch in the dark. If it's not on, check the connection of the blue wire to the battery positive.
