  • Faulty alternator.
  • Corroded battery terminals.
Tools Required:
  • Multimeter.
  • Wire brush and terminal cleaner.
  • Basic hand tools.

Repair Instructions:

  1. Clean battery terminals with a wire brush if corroded.
  2. Replace the battery if it is weak (below 12V).
  3. Replace the alternator if it fails to produce sufficient voltage.
3. Oil Pressure Warning Light
Common Causes:
  • Low oil level.
  • Faulty oil pressure sensor.
  • Oil pump failure.
Tools Required:
  • Oil pressure gauge.
  • Basic hand tools.
  • Oil and filter (if low).

Repair Instructions:
