Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is in a safe, well-ventilated area.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection

Sub-step 1: Clean the battery terminals with a wire brush if corrosion is present.
Sub-step 2: Reconnect the battery terminals and ensure they are tight.
Sub-step 3: If the battery fails the load test, replace it with a new battery of the correct specifications.

3. Starter Motor Replacement

Sub-step 1: Locate the starter motor, typically mounted on the engine block near the transmission.
Sub-step 2: Disconnect the electrical connectors from the starter.
Sub-step 3: Remove the mounting bolts securing the starter motor to the engine using a socket set.
Sub-step 4: Carefully remove the starter motor from its mounting position.
Sub-step 5: Install the new starter motor by reversing the removal steps, ensuring all connections are secure.

4. Relay and Fuse Replacement

Sub-step 1: If the starter relay was faulty, replace it with a new relay of the same specifications.
Sub-step 2: Replace any blown fuses with fuses of the appropriate amperage as specified in the owner’s manual.

5. Final Check

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Start the vehicle to verify that the clicking noise is resolved and the engine starts smoothly.
