Setup
Before beginning installation, ensure you have the necessary tools and materials. Safety precautions should always be observed when working with electrical components.
Required Tools and Materials
- Gardner Bender 10-103 Electrical Ring Terminals
- Wire strippers/cutters (appropriate for 16-14 AWG wire)
- Crimping tool (designed for insulated terminals)
- Electrical wire (16-14 AWG)
- Safety glasses
Preparation Steps
- Power Disconnection: Ensure all power to the circuit is disconnected before working with wires.
- Wire Inspection: Inspect the wire for any damage or fraying. Use only undamaged wire.
- Wire Stripping: Using wire strippers, carefully remove approximately 3/8 to 1/2 inch (10-12 mm) of insulation from the end of the wire. Ensure the stripped wire strands are clean and untwisted.
Operating Instructions
Follow these steps to properly crimp the Gardner Bender 10-103 Electrical Ring Terminal onto your wire.
- Insert Wire: Insert the stripped end of the wire into the barrel of the ring terminal. Ensure all wire strands are fully inserted into the metal barrel and that the insulation meets the edge of the terminal's insulation barrel.
- Position for Crimping: Place the terminal into the appropriate crimping jaw of your crimping tool. For 16-14 AWG insulated terminals, use the blue-coded crimp slot on your tool. The crimp should be applied to the metal barrel section of the terminal.
- Crimp the Terminal: Firmly squeeze the handles of the crimping tool until the crimp cycle is complete. A proper crimp will securely fasten the wire within the terminal.
- Verify Connection: After crimping, gently pull on the wire to ensure it is securely held by the terminal. The connection should be tight and not pull free. The insulation should be intact and not damaged by the crimping process.
- Final Installation: Connect the ring terminal to the desired stud or screw, ensuring a tight and secure mechanical and electrical connection.

Maintenance
Gardner Bender electrical ring terminals are designed for long-lasting performance. Minimal maintenance is required, but periodic inspection can help ensure continued reliability.
- Visual Inspection: Periodically inspect installed terminals for any signs of corrosion, discoloration, or physical damage to the insulation or metal.
- Connection Tightness: Ensure that the terminal remains securely fastened to its connection point. Loose connections can lead to overheating and electrical issues.
- Storage: Store unused terminals in a dry environment, away from direct sunlight and extreme temperatures, to prevent degradation of the insulation material.
Troubleshooting
If you encounter issues during or after installation, consider the following common problems and solutions.
- Loose Connection:
- Cause: Insufficient crimping force, incorrect crimping tool, or improper wire stripping.
- Solution: Ensure the correct crimping tool is used for insulated terminals and that sufficient force is applied. Verify the wire is stripped to the correct length and fully inserted. Re-crimp if necessary, or use a new terminal.
- Wire Pulls Out:
- Cause: Inadequate crimp, wrong wire gauge for the terminal, or damaged wire strands.
- Solution: Confirm the wire gauge (16-14 AWG) matches the terminal. Ensure the crimp is firm and the wire strands are not damaged. Always perform a gentle pull test after crimping.
- Damaged Insulation:
- Cause: Incorrect crimping tool setting or excessive force.
- Solution: Use the correct crimping die for insulated terminals. Adjust crimping tool pressure if possible. Replace any terminal with damaged insulation to prevent electrical shorts.
