6. Setup and Installation
Follow these steps for proper installation of your fuse block:
- Choose a Mounting Location: Select a dry, protected area in your vehicle or boat that is easily accessible for maintenance. Ensure sufficient space for wiring.
- Mount the Fuse Block: Use the provided screws to securely fasten the fuse block to a flat surface.
- Open the Cover: Press the black latch on the side of the cover to release and remove it.
- Install Fuses: Insert the appropriate amperage blade fuses into each desired circuit slot. Ensure they are firmly seated.
- Connect Main Power:
- Connect the main positive (+) power cable from your battery or power source to the main positive terminal on the fuse block.
- Connect the main negative (-) ground cable from your battery or chassis ground to the main negative terminal on the fuse block.
- Wire Individual Circuits:
- For each accessory, connect its positive (+) wire to one of the individual positive output terminals (where the fuses are located).
- Connect the negative (-) wire of each accessory to one of the individual negative terminals on the negative bus bar.
- Apply Labels: Use the provided label stickers to clearly identify each circuit for easy reference.
- Secure the Cover: Replace the clear protective cover, ensuring it latches securely to protect the fuses and wiring.

7. Operating Instructions
The KAOLALI 12-Way Marine Fuse Block is designed for straightforward operation.
- Power Distribution: Once properly wired, the fuse block distributes power from your main source to up to 12 individual accessories, each protected by its own fuse.
- LED Indicator Function: If a fuse blows due to an overcurrent condition, the corresponding red LED indicator next to that fuse will illuminate. This allows for quick identification of the faulty circuit without needing to test each fuse individually.
- Fuse Replacement: To replace a blown fuse, first disconnect power to the fuse block. Open the cover, carefully remove the blown fuse, and insert a new fuse of the exact same amperage rating. Close the cover and restore power.

8. Maintenance
Regular maintenance ensures the longevity and reliable performance of your fuse block.
- Keep Clean: Periodically wipe the exterior of the fuse block and cover with a dry, soft cloth to remove dust and debris.
- Inspect Connections: Annually, or as needed, inspect all wiring connections to ensure they remain tight and free from corrosion. Loose connections can cause overheating or intermittent power issues.
- Check Fuses: While the LED indicators help identify blown fuses, a visual inspection of all fuses during routine maintenance is recommended to ensure they are properly seated and intact.
- Cover Integrity: Ensure the protective cover is always securely latched to maintain its waterproof and dustproof properties.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Accessory not receiving power. | Blown fuse. | Check the LED indicator for the affected circuit. If lit, replace the fuse with one of the correct amperage. |
| Accessory not receiving power. | Loose or corroded wiring connection. | Inspect all positive and negative connections for the circuit and tighten as necessary. Clean any corrosion. |
| LED indicator is always on, even with a new fuse. | Short circuit in the accessory or wiring. | Disconnect the accessory and inspect its wiring for shorts. Repair or replace the faulty component. |
| Multiple fuses blowing frequently. | Overload on circuits or main power. | Ensure the total current draw does not exceed the fuse block's capacity. Redistribute loads or consider a higher capacity fuse block if necessary. Inspect all connected accessories for faults. |
