Solution

1. Preparation

Gather necessary tools and parts.
Ensure safety gear is worn (gloves, safety glasses).
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Maintenance

Tools Required: Wrench (for battery terminal).
Clean any corrosion from battery terminals using a wire brush.
Tighten the battery terminal connections securely.

3. Starter Motor Inspection

Tools Required: Socket set, multimeter.
Remove the starter motor from the vehicle by unbolting it from the engine block.
Inspect the starter for signs of wear or damage.
Test the starter solenoid by applying direct battery voltage to it and checking for operation.

4. Replace Components (if necessary)

If the battery or starter is faulty:
- Tools Required: Socket set, torque wrench.
- Remove the old battery/starter and install the new one, ensuring all connections are tight and secured.
- Torque the starter bolts to the manufacturer’s specifications (typically around 20-30 lb-ft).

5. Reconnect Battery

Reconnect the negative battery terminal.
Ensure all tools are removed from the engine bay before starting the vehicle.
