Solution
1. Preparation
  • Gather tools and parts needed for repair.
  • Ensure the vehicle is parked on a flat surface, and the engine is off.
  • Disconnect the negative battery terminal to prevent electrical shock.
2. Inspect Battery and Connections
  • Remove the battery terminals, starting with the negative terminal.
  • Clean the terminals and battery posts with a wire brush to remove corrosion.
  • Reconnect the terminals securely and ensure they are tight.
3. Test and Replace Alternator (if necessary)
  • Use a multimeter to measure the voltage at the battery with the engine running; it should read between 13.7 to 14.7 volts.
  • If the voltage is lower, remove the alternator:
    • Disconnect wiring harness and battery connections.
    • Remove the alternator mounting bolts (typically 10-13mm).
    • Carefully extract the alternator from the engine bay.
  • Install the new alternator by reversing the removal steps.
  • Torque the alternator bolts to the manufacturer specifications (usually around 37 Nm).
4. Check and Replace Fuses
  • Locate the fuse box (usually under the dashboard or in the engine compartment).
  • Identify and inspect fuses related to the dashboard lights and electrical system.
  • Replace any blown fuses with the same amperage rating.
5. Inspect Wiring and Ground Connections
  • Visually inspect wiring harnesses for any signs of wear, fraying, or damage.
  • Tighten or clean any loose ground connections, typically found near the battery or engine block.
