Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts during the process.

2. Inspect Battery Connections

Tools Required: Wrench or socket set.
Remove the positive (+) and negative (-) battery terminals.
Clean any corrosion from the battery terminal and post using a wire brush.
Reconnect the battery terminals securely.

3. Check and Replace the Battery (if necessary)

Tools Required: Multimeter, battery terminal cleaner, socket set.
If the battery voltage is below 12.4 volts, consider replacing the battery.
Remove the old battery by unfastening the hold-down clamp and disconnecting the terminals.
Install the new battery by connecting the positive terminal first, followed by the negative terminal.

4. Check and Replace the Alternator (if necessary)

Tools Required: Socket set, multimeter.
If the alternator output was below 13.7 volts, it may need replacement.
Disconnect the negative battery terminal again.
Remove the serpentine belt from the alternator by using a belt tensioner tool.
Unscrew the mounting bolts and disconnect the electrical connections from the alternator.
Install the new alternator by reversing the removal process and ensuring all connections are secure.

5. Reconnect Battery and Reset Light

Reconnect the negative battery terminal.
Start the engine and check if the battery light is still illuminated.
If the light remains on, perform a reset by disconnecting the battery for 10-15 minutes.
