Solution

1. Preparation

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

2. Inspect and Clean Battery Terminals

Tools Required: Wire brush, terminal cleaner, and wrench.
Remove the positive terminal first, followed by the negative.
Clean the terminals and battery posts thoroughly to remove corrosion.
Reattach the terminals securely, starting with the positive terminal.

3. Test and Replace the Battery (if necessary)

Tools Required: Multimeter.
Measure the battery voltage; if below 12.4 volts, consider replacing the battery.
Remove the old battery using a wrench and install a new one. Secure it in place.

4. Check and Replace the Alternator (if necessary)

Tools Required: Socket set and multimeter.
Disconnect the battery again for safety.
Remove the alternator belt by loosening the tensioner pulley.
Disconnect the electrical connectors from the alternator.
Remove the alternator mounting bolts and take out the alternator.
Install the new alternator by reversing the steps and reconnecting all electrical connections.

5. Inspect Wiring and Fuses
