Setup & Installation
Proper installation is crucial for the safe and efficient operation of your Tiardey 12V Fuse Box. Follow these steps carefully.
Wiring Instructions
- Main Power Connection: Connect the main input wires of the fuse box directly to your vehicle's 12V power source. The red wire is for positive (+), and the black wire is for negative (-). Ensure a secure connection to prevent power loss or short circuits.
- Device Connections: The fuse box provides four independent output channels (No.1 to No.4). Connect your electrical devices (e.g., headlights, navigation systems, phone chargers) to these output terminals. Each channel has a positive (+) and negative (-) terminal.
- Fuse Installation: Ensure appropriate fuses are installed in each channel according to the current requirements of the connected device. The fuse box is designed to protect your devices from overcurrent.

Mounting
The compact design of the fuse box allows for flexible mounting. Use the provided cable ties or 3M adhesive pads to secure the unit in a suitable location within your vehicle, ensuring it is away from excessive heat, moisture, and moving parts.
Operation
The Tiardey 12V Fuse Box is designed for straightforward operation, primarily indicated by its intelligent light system.
Indicator Lights
- Blue Light: When a circuit is active and functioning normally, the corresponding blue indicator light will illuminate. This confirms that power is flowing correctly to the connected device.
- Red Light: If a fuse blows or a circuit experiences a disconnection, the corresponding red indicator light will illuminate. This feature quickly identifies the faulty circuit, allowing for immediate troubleshooting and replacement of the specific fuse.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your fuse box.
- Regular Inspection: Periodically check all wiring connections to ensure they are secure and free from corrosion.
- Cleaning: Keep the fuse box clean and free from dust, dirt, and moisture. Use a dry, soft cloth for cleaning. Do not use abrasive cleaners or solvents.
- Fuse Replacement: If a red indicator light illuminates, it signifies a blown fuse. Disconnect power to the fuse box before replacing the faulty fuse with a new one of the correct amperage. Always use fuses with the specified rating to avoid damage to the fuse box or connected devices.
Troubleshooting
This section addresses common issues you might encounter with your Tiardey 12V Fuse Box.
| Problem | Possible Cause | Solution |
|---|---|---|
| No indicator lights illuminate when power is applied. | No main power supply to the fuse box, or incorrect wiring. | Check the main power connections (red to positive, black to negative) and ensure the vehicle's 12V power source is active. |
| A red indicator light is on for a specific channel. | The fuse for that channel is blown, or there is a short circuit/overload in the connected device. | Identify the faulty device. Disconnect power, replace the blown fuse with one of the correct amperage. If the fuse blows again immediately, check the connected device for a short circuit. |
| Connected device is not working, but blue light is on. | Issue with the connected device itself, or poor connection between the device and the fuse box output. | Check the device's own power and functionality. Ensure the device's wires are securely connected to the fuse box output terminals. |
