Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect Battery and Connections

• Sub-steps:
  • Remove the battery cover if applicable.
  • Clean any corrosion on the battery terminals using a wire brush and a mixture of baking soda and water.
  • Reconnect the terminals securely.
• Tools Required: Wire brush, baking soda, water, wrench.

3. Test and Replace Battery if Necessary

• Sub-steps:
  • Use a multimeter to measure the battery voltage. If it reads below 12.4 volts, consider replacing the battery.
  • If the battery is faulty, remove it using a wrench and replace it with a new one, ensuring the correct specifications are met.
• Tools Required: Multimeter, wrench.

4. Check and Replace Alternator if Faulty

• Sub-steps:
  • Start the engine and use the multimeter to check the voltage at the battery terminals. If it is below 13.8 volts, the alternator may be defective.
  • Remove the alternator belt and then the alternator itself using a socket set.
  • Install the new alternator in reverse order, ensuring proper tension on the belt.
• Tools Required: Socket set, wrench, torque wrench.

5. Inspect Wiring and Ground Connections
