Solution

1. Preparation

Tools Required:
- Multimeter
- Socket set
- Wrench set
- Wire brush or battery terminal cleaner
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection

Sub-steps:
1. Clean the battery terminals with a wire brush to remove corrosion.
2. Reconnect the battery terminals securely.
3. If the battery voltage is low, jump-start the vehicle or replace the battery.

3. Starter Relay and Solenoid Check

Sub-steps:
1. Locate the starter relay in the fuse box.
2. Swap it with a similar relay to test functionality.
3. If the clicking persists, locate the starter solenoid on the starter motor.
4. Using a multimeter, check for voltage at the solenoid while attempting to start the vehicle.

4. Starter Replacement (if necessary)

Sub-steps:
1. If the starter is faulty, disconnect the negative battery terminal again.
2. Remove the starter motor by unscrewing the mounting bolts using the socket set.
3. Disconnect the wiring harness from the starter.
4. Install the new starter by reversing the removal steps and ensuring all connections are tight.
5. Torque the starter mounting bolts to manufacturer specifications (typically around 20-25 ft-lbs).
