Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the ignition is off.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection and Replacement

Inspect the Battery:
- Clean terminals using a wire brush if corrosion is present.
- Verify battery voltage with a multimeter; if below 12.4 volts, consider recharging or replacing the battery.
Test Battery Load:
- Use a battery load tester to check if the battery can hold a charge under load.
- If the battery fails the load test, replace it with a new, compatible battery.

3. Starter Motor and Wiring Inspection

Check Starter Motor:
- With the battery reconnected, locate the starter motor.
- Use a wrench to directly connect the battery positive terminal to the starter motor terminal to see if the motor engages.
Inspect Wiring Connections:
- Ensure all wiring connections to the starter and battery are secure and not corroded.
- Tighten any loose connections as necessary.

4. Replace Starter Motor (if necessary)

Remove the Starter:
- Disconnect the negative battery terminal again.
- Unbolt the starter from its mount using the appropriate socket set.
- Disconnect wiring harnesses from the starter.
Install New Starter:
- Position the new starter in place and reconnect the wiring harnesses.
- Bolt the starter securely and reconnect the negative battery terminal.

5. Final Checks

Recheck all connections and ensure everything is secure.
Start the vehicle to verify the repair.
