Safety Warnings: Always wear safety goggles and gloves when working with batteries. Ensure the vehicle is in park and the ignition is off before starting.

2. Battery Replacement (if necessary)

Disconnect Battery:
- Use a socket set to loosen and remove the negative terminal first, followed by the positive terminal.
Remove Old Battery:
- Unfasten any securing brackets or clamps holding the battery in place.
- Carefully lift the battery out of the vehicle.
Clean Battery Tray and Terminals:
- Use a wire brush to clean any corrosion from the battery tray and terminals.
Install New Battery:
- Place the new battery in the tray and secure it with brackets or clamps.
- Reconnect the positive terminal first, followed by the negative terminal.
Test New Battery:
- Use the multimeter to ensure the new battery reads 12.6 volts or higher.

3. Charging System Check

Inspect Alternator:
- Visually inspect the alternator for any loose wires or signs of damage.
Test Alternator Output:
- Start the vehicle and use the multimeter to measure the voltage at the battery. It should read between 13.8 to 14.4 volts while running.
