Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the vehicle battery to ensure safety while working on electrical components.

Tools Required:

  • Multimeter
  • Socket set
  • Screwdriver set
  • Wire strippers and connectors (if needed)
2. Inspect and Replace Headlight Bulbs
  • Remove the headlight housing by unscrewing the retaining screws.
  • Carefully disconnect the wiring harness from the back of the headlight.
  • Remove the old bulb and inspect for damage or burnt filaments.
  • Install the new bulb (ensure it matches OEM specifications).
  • Reconnect the wiring harness and secure the headlight housing back in place.
3. Check Battery and Alternator
  • Reconnect the battery and use a multimeter to check the battery voltage.
  • Start the engine and measure the voltage at the battery again; it should read between 13.7V and 14.7V.
  • If the voltage is low, inspect the alternator connections and ground wires. Replace the alternator if it fails to produce the correct voltage.
4. Inspect Wiring and Connections
  • Trace the headlight wiring harness from the bulbs to the fuse box.
  • Look for any signs of wear, corrosion, or loose connections.
  • Repair any damaged wires using wire strippers and connectors as necessary.
