• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface with the engine off.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Headlight Bulbs

  1. Remove the headlight assembly by unscrewing any retaining screws and disconnecting the wiring harness.
  2. Remove the old bulb by twisting it counterclockwise and pulling it out.
  3. Install the new bulb by aligning it properly and twisting it clockwise to secure.
  4. Reconnect the wiring harness and reinstall the headlight assembly.
• Tools Required: Screwdriver set
• Parts Required: New headlight bulbs

3. Check and Repair Wiring Harness

• Sub-steps:
  1. Visually inspect the wiring harness for frayed wires or loose connections.
  2. Repair any damaged wiring with electrical tape or replace sections as necessary.
  3. Ensure all connections are secure before reassembling any components.
• Tools Required: Wire cutters, electrical tape, soldering iron (if necessary)

4. Test Battery and Alternator

• Sub-steps:
  1. Reconnect the battery and start the engine.
  2. Use a multimeter to check the battery voltage; it should read around 12.6 volts with the engine off.
  3. With the engine running, check the alternator output; it should read between 13.8 and 14.4 volts.
  4. If readings are outside this range, consider replacing the battery or alternator.
