Solution

1. Preparation

Tools Required: Socket set, multimeter, wire brush or terminal cleaner, safety gloves, and safety goggles.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

Disconnect the negative terminal of the battery to prevent arcing.
Clean the battery terminals using a wire brush to remove any corrosion.
Reconnect the terminals securely, starting with the positive terminal first.

3. Testing the Starter Motor

Locate the starter motor, usually found near the transmission on the engine block.
Disconnect the wiring harness from the starter motor.
Use a multimeter to check for voltage at the starter motor terminal while a helper turns the ignition key to the start position. You should see battery voltage (around 12 volts).
If voltage is present but the starter does not engage, proceed to replace the starter motor.

4. Replacing the Starter Motor (if necessary)

Disconnect the negative battery terminal again.
Remove the starter motor by unbolting it from the engine block (typically requires a socket set).
Carefully disconnect the electrical connections from the starter.
Install the new starter by reversing the removal steps, ensuring all connections are secure.
Torque the bolts to the manufacturer’s specifications (usually around 30-40 Nm).

5. Final Checks

Reconnect the negative battery terminal.
Start the vehicle to verify that the clicking noise has been resolved and the engine starts smoothly.
