Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection

Sub-steps:
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion from the terminals and battery posts using a wire brush.
- Reconnect the terminals securely, ensuring tight connections.

3. Starter Relay Check

Sub-steps:
- Locate the starter relay in the fuse box (refer to the owner's manual for exact location).
- Remove the relay and inspect for any physical damage.
- Replace with a new relay if necessary, or swap with a similar relay to test functionality.

4. Starter Motor Testing

Sub-steps:
- Locate the starter motor and check wiring connections for security and corrosion.
- Use a multimeter to measure voltage at the starter motor when attempting to start the vehicle.
- If no voltage is present, further investigate the ignition switch and wiring.

5. Replace Starter (if necessary)

Sub-steps:
- If the starter is faulty, remove the mounting bolts and electrical connections to the starter.
- Install a new starter motor, securing it with the bolts to the manufacturer's torque specifications.
- Reconnect electrical connections ensuring they are tight and free of corrosion.

Tools Required:
