Solution

1. Preparation

Gather tools: multimeter, load tester, wrench set, socket set, and safety gloves.
Ensure the vehicle is in a safe location, parked on a flat surface, and the ignition is turned off.

2. Battery Inspection

1.1 Disconnect the negative battery terminal using a wrench to prevent electrical shorts.
1.2 Remove the positive battery terminal and inspect both terminals for corrosion. Clean any corrosion with a mixture of baking soda and water.
1.3 Reconnect the terminals securely, ensuring no loose connections are present.

3. Battery Testing

3.1 Use a multimeter to test the battery voltage; if below 12.4 volts, charge the battery using an appropriate battery charger.
3.2 If the battery is over 4 years old or shows weak performance on the load tester, consider replacing it with a new battery.

4. Starter and Electrical System Check

4.1 Inspect and tighten all connections to the starter motor.
4.2 If the connections are secure, test the starter motor by applying direct voltage to the starter terminal (ensure safety precautions).
4.3 If the starter motor is defective, replace it with a new starter.

5. Final Steps

5.1 Reconnect the battery terminals in the correct order (positive first, then negative).
5.2 Start the vehicle and check if the clicking sound persists.
