Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Inspect and Replace Headlight Bulbs
  • Remove the headlight assembly by undoing any retaining screws or clips.
  • Disconnect the wiring harness from the bulb socket.
  • Remove the old bulbs and install new ones (ensure proper wattage).
  • Reconnect the wiring harness and reassemble the headlight assembly.
3. Test Battery and Alternator

4. Repair Wiring Connections
  • Inspect and clean any corroded connectors using electrical cleaner.
  • Replace any damaged wiring with appropriate gauge wire and connectors.
  • Ensure all connections are tight, especially the ground connection.
5. Final Assembly and Testing
