Solution

1. Preparation

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

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Use a wire brush to clean any corrosion from the terminals and cable ends.
3. If the battery is found to be defective, replace it with a new, fully charged battery of the correct type.
4. Reconnect battery terminals (positive first, then negative), ensuring they are securely tightened.

3. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor, usually found near the engine block.
2. Inspect the wiring harness and connections for wear or loose connections.
3. If necessary, remove the starter motor by unbolting it from its mounting (ensure all connections are disconnected).
4. Test the starter motor's functionality by applying power directly; if it does not engage, replace the starter motor.

4. Electrical System Check

Sub-steps:
1. Check and replace any blown fuses related to the starting system.
2. Inspect relays for the starter system and replace any that are faulty.
3. If all checks are satisfactory but the vehicle still does not start, consider testing the ignition switch.
