2. Clean the terminals and battery posts with a wire brush.
3. Test the battery with a multimeter; if below 12.4 volts, replace it.
4. Install the new battery by connecting the positive terminal first, followed by the negative.
Tools Required: Multimeter, wire brush, socket set.

3. Starter and Relay Inspection

Sub-steps:
1. Locate the starter relay in the fuse box; swap with a functioning relay.
2. If the clicking persists, remove the starter motor from the engine.
3. Inspect the starter for wear or damage; replace if necessary.
4. Reinstall the starter and connect the wiring securely.
Tools Required: Socket set, torque wrench.

4. Testing the Ignition System

Sub-steps:
1. Verify that the ignition switch is functioning by checking for continuity with a multimeter.
