Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked in a safe location with the engine off.
Disconnect the battery to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
1. Remove the negative (-) terminal first, followed by the positive (+) terminal.
2. Clean any corrosion from the terminals and cable ends using a wire brush.
Test Battery:
1. Reconnect the battery terminals.
2. Use a multimeter to check the voltage. If it reads below 12.4 volts, consider charging or replacing the battery.
Replace Battery (if necessary):
1. Remove the old battery from the vehicle.
2. Install the new battery by connecting the positive (+) terminal first, followed by the negative (-) terminal.
3. Ensure the battery is secured in place.

3. Starter Motor Inspection and Replacement
