Solution

1. Preparation

• Gather tools: multimeter, socket set, wrench set, battery terminal cleaner.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Allow the vehicle to cool if it has been running recently.

2. Battery Inspection

• Sub-step 1: Clean the battery terminals using a battery terminal cleaner to remove corrosion.
• Sub-step 2: Reconnect the battery terminals securely.
• Sub-step 3: Use a multimeter to measure the battery voltage; recharge or replace the battery if voltage is low (below 12.4 volts).

3. Starter Motor Test

• Sub-step 1: Locate the starter motor, usually near the transmission bell housing.
• Sub-step 2: Disconnect the wiring harness from the starter motor.
• Sub-step 3: Use jumper cables to connect the starter motor directly to the battery to see if it engages.
• Sub-step 4: If the starter clicks but does not turn, replace the starter motor.

4. Wiring and Ignition Check

• Sub-step 1: Inspect the wiring harness leading to the starter motor for frays or breaks.
• Sub-step 2: Test the ignition switch by using a multimeter to check for continuity when the key is turned.
• Sub-step 3: Replace any defective components identified during the inspection.

5. Final Assembly

• Sub-step 1: Reconnect all wiring and ensure all connections are tight.
• Sub-step 2: Reconnect the negative battery terminal.
• Sub-step 3: Attempt to start the vehicle.
