Safety Information
Always observe the following safety precautions when working with electrical components:
- Disconnect power before installing or removing terminals.
- Wear appropriate personal protective equipment, including safety glasses and gloves.
- Ensure wires are of the correct gauge (16-14 AWG) for these terminals to prevent improper connections or electrical hazards.
- Avoid touching live electrical circuits.
- Consult a qualified professional if you are unsure about any installation steps.
Setup and Installation
Proper installation is crucial for a secure and reliable electrical connection. Follow these steps carefully:
Tools Required:
- Wire Strippers (for 16-14 gauge wire)
- Crimping Tool (for insulated terminals)
- Wire Cutters
Installation Steps:
- Prepare the Wire: Using wire strippers, carefully strip approximately 1/4 to 3/8 inch (6-9 mm) of insulation from the end of the 16-14 gauge wire. Ensure the copper strands are clean and untwisted.
- Insert Wire into Terminal: Insert the stripped end of the wire into the metal barrel of the bullet terminal. Ensure all wire strands are inside the barrel and that the insulation butts up against the terminal's insulation sleeve.
- Crimp the Terminal: Place the terminal into the appropriate crimping jaw of your crimping tool (usually marked for insulated terminals or specific wire gauges). Squeeze the handles firmly until the crimp is complete. A proper crimp should be tight and secure, holding the wire firmly without damaging the insulation.
- Test the Connection: Gently tug on the wire to ensure it is securely fastened within the terminal. The wire should not pull out.
- Connect Terminals: Align the male bullet terminal with the female bullet terminal and push them together until they are fully seated. A secure connection should feel firm.

Operating and Usage
Once properly installed, Dorman 85449 bullet terminals provide a reliable and easily disconnectable electrical connection. They are commonly used in automotive wiring for accessories, lighting, and other low-voltage applications where a quick connect/disconnect feature is beneficial. Ensure that the current and voltage ratings of your application do not exceed the capabilities of the 16-14 gauge wire and the terminals themselves.
Maintenance
To ensure the longevity and optimal performance of your Dorman bullet terminals, consider the following maintenance tips:
- Regular Inspection: Periodically inspect connections for signs of corrosion, loose wires, or physical damage.
- Keep Dry: While the terminals have insulation, prolonged exposure to moisture can lead to corrosion. Ensure connections are in a dry environment or adequately protected.
- Clean Contacts: If corrosion is present, disconnect the terminals and gently clean the metal contacts with a fine-grit abrasive or electrical contact cleaner. Ensure terminals are dry before reconnecting.
- Avoid Over-stressing: Do not pull on the wires to disconnect the terminals; always grasp the terminal bodies.
Troubleshooting
If you encounter issues with your electrical connection, refer to the following table:
| Problem | Possible Cause | Solution |
|---|---|---|
| No electrical continuity | Loose crimp, corroded contacts, incorrect wire gauge, damaged wire. | Re-crimp the terminal, clean contacts, verify wire gauge, inspect and replace damaged wire. |
| Terminals disconnect easily | Improper connection, worn terminals, incorrect terminal size. | Ensure terminals are fully seated, replace worn terminals, verify correct .250 inch bullet size. |
| Overheating at connection point | Loose connection, undersized wire/terminal for current load, corrosion. | Ensure tight connection, verify wire and terminal are rated for the current, clean corrosion. |
