Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery cable to ensure safety.
  • Allow the vehicle to sit for a short time if recently used to avoid burns from hot components.
2. Battery Inspection and Replacement
  1. Inspect Battery Condition

    • Remove battery terminals (positive first, then negative).
    • Clean terminals with a wire brush if corroded.
    • Use a multimeter to check voltage.
    • If the voltage is low, proceed to replace the battery.
  2. Replace Battery (if needed)

    • Remove the old battery from the vehicle.
    • Place the new battery in the tray.
    • Reconnect terminals (negative first, then positive).
    • Ensure tight connections to prevent future issues.
3. Starter Motor Testing and Replacement
  1. Test Starter Motor

    • Locate the starter motor and inspect its wiring.
    • Use a multimeter to check for voltage at the starter when the key is turned.
    • If no voltage or the starter is faulty, proceed to replace.
  2. Replace Starter Motor

    • Disconnect battery again.
    • Remove starter motor bolts and take out the starter.
    • Install the new starter motor and secure with bolts.
    • Reconnect battery and test the starter function.
4. Alternator Testing and Replacement
  1. Test Alternator Output

    • Reconnect battery and start the engine.
    • Use a multimeter to measure voltage at the battery with the engine running (should be 13.5-14.5V).
    • If output is low, replace the alternator.
  2. Replace Alternator

    • Disconnect battery again.
    • Remove the serpentine belt from the alternator.
    • Unbolt and remove the alternator.
    • Install new alternator and reconnect the belt.
    • Reconnect battery and verify output.
