NOCO GC017 15A 14AWG 12V Adapter with Battery Clamps Instruction Manual
Model: GC017
Introduction
The NOCO GC017 12V Adapter with Battery Clamps is designed to provide a convenient 12-volt power source directly from your vehicle's battery. This adapter allows you to power various 12-volt devices such as tire inflators, vacuum cleaners, coffee makers, and fans. It features a robust design with a 20-amp micro-blade fuse for enhanced safety and a water-resistant cap to protect the female socket from environmental elements. Constructed with high-conductivity 14AWG 100-percent copper wire, it is rated for a capacity of 15 amperes.
Safety Information
- Always ensure proper polarity when connecting the clamps to the battery terminals. Connect the red (+) clamp to the positive battery terminal and the black (-) clamp to the negative battery terminal.
- Do not short-circuit the battery clamps.
- Ensure the 12-volt device you are connecting does not exceed the adapter's 15-ampere rating.
- Keep the adapter and its connections dry and clean. The water-resistant cap should be used when the socket is not in use.
- Do not modify the adapter or its components.
- Store the adapter in a cool, dry place away from direct sunlight and extreme temperatures.

Optional: Hard-Mounting with M6 Eyelets
For a more permanent connection, the included M6 eyelets can be used to hard-mount the adapter to your battery terminals. This is particularly useful for motorcycles, ATVs, or other applications where a semi-permanent 12V power port is desired.
- Disconnect the battery clamps from the adapter cable by unscrewing the terminal bolts using the provided 3mm hex wrench.
- Attach the M6 eyelets to the adapter cable, ensuring the red eyelet connects to the red wire and the black eyelet to the black wire. Secure them with the terminal bolts.
- Connect the red M6 eyelet to the positive battery terminal and the black M6 eyelet to the negative battery terminal. Ensure a tight and secure connection.
- The 12V female socket is now available for use.

Maintenance
- Cleaning: Periodically clean the battery clamps and the female socket with a dry cloth to remove any dirt or corrosion. Ensure the adapter is disconnected from the battery before cleaning.
- Storage: When not in use, store the GC017 adapter in a clean, dry environment. Ensure the water-resistant cap is securely in place over the female socket.
- Inspection: Regularly inspect the cable for any signs of damage, cuts, or fraying. Check the clamps and eyelets for secure connections and any signs of wear. Do not use if damaged.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not receiving power. |
|
|
| Adapter feels warm during use. | High current draw from connected device. | This can be normal for high-power devices. Ensure the device does not exceed the 15A rating. If it becomes excessively hot, disconnect immediately. |
Fuse Replacement
The GC017 features an integrated 20-amp micro-blade fuse for protection. If the adapter stops providing power, the fuse may have blown.
- Disconnect the GC017 from the battery.
- Locate the fuse holder along the red wire.
- Open the fuse holder and carefully remove the old fuse.
- Insert a new 20-amp micro-blade fuse (ATO/ATC type) into the holder.
- Close the fuse holder securely.
- Reconnect the adapter to the battery and test.
