Repair Instructions

Step 1: Clean and Secure Connections

1. Disconnect the Battery

   • Remove the negative terminal from the battery to prevent any electrical shorts.

2. Inspect and Clean Ground Connections

   • Locate the ground connection for the headlights (usually found near the front of the vehicle).
   • Remove the ground connection, clean the area with a wire brush or sandpaper, and reattach securely.

3. Check Headlight Harness

   • Inspect the headlight connectors for corrosion or damage. Clean any corrosion with a contact cleaner.

Step 2: Replace Headlight Bulbs (if necessary)

1. Access Headlight Assembly

   • Open the hood and locate the headlight assembly.
   • Depending on the design, you may need to remove screws or clips to access the headlight bulbs.

2. Remove Old Bulbs

   • Disconnect the wiring harness from the bulb.
   • Rotate the bulb socket counterclockwise to release it from the assembly and remove the bulb.

3. Install New Bulbs

   • Insert the new bulb into the socket, making sure not to touch the glass with your fingers (oil can shorten bulb life).
   • Rotate the socket clockwise to secure it back into the assembly.
   • Reconnect the wiring harness.

Step 3: Test Headlights

1. Reconnect Battery

   • Reattach the negative battery terminal.

2. Test Headlights

   • Turn on the headlights to check for brightness and proper operation.
   • Observe for any flickering or dimming.

3. Further Testing (If Still Dim)

   • If headlights are still dim, recheck the voltage drop across the circuit.
   • If a significant drop is detected, consider inspecting the wiring for damage or replacing the headlight relay.
