Solution

1. Preparation

Gather tools and ensure the vehicle is in a safe working environment.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Battery Terminals

Tools Required: Wire brush, battery terminal cleaner
Remove any corrosion from the battery terminals using a wire brush.
Ensure the battery cables are securely attached and free from damage.
Reconnect the battery terminals securely.

3. Test the Battery

Tools Required: Multimeter
Disconnect the battery and use a multimeter to test the battery voltage; if below 12.4 volts, replace the battery.
If the battery is functional, proceed to the next step.

4. Check the Alternator

Tools Required: Multimeter, socket set
Start the engine and measure the voltage at the battery terminals; it should read between 13.5 to 14.5 volts.
If the reading is low, replace the alternator. To replace:
1. Disconnect the negative battery terminal.
2. Remove the alternator drive belt using a serpentine belt tool.
3. Unplug the electrical connector from the alternator.
4. Remove the mounting bolts and take out the alternator.
5. Install the new alternator and reverse the removal steps.

5. Inspect Fuses

Tools Required: Fuse puller or pliers
Check and replace any blown fuses related to the charging system as indicated in the vehicle's fuse box diagram.
