Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is in a safe, well-ventilated area.
Disconnect the battery before starting work to prevent electrical shock.

2. Inspect and Clean Battery Terminals

Remove the battery terminals, starting with the negative terminal followed by the positive.
Clean the terminals and cable ends using a wire brush to remove corrosion.
Reattach the terminals securely after cleaning.

3. Replace the Battery (if necessary)

Remove Old Battery:
- Loosen and remove the battery hold-down bracket.
- Carefully lift the old battery out of the tray and place it on a flat surface.
Install New Battery:
- Place the new battery in the tray, ensuring proper orientation.
- Reinstall the hold-down bracket and tighten it to secure the battery.
Reconnect Battery:
- Connect the positive terminal first, followed by the negative terminal.

4. Test the Electrical System

Start the vehicle and monitor all electrical components for proper function.
Use a multimeter to check the alternator output again, ensuring it charges the battery within the range of 13.7 to 14.7 volts.
