Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Tools Required: Wrench set, multimeter, battery charger.
Sub-steps:
1. Remove corrosion from battery terminals using a wire brush.
2. Reconnect the battery terminals securely and test the voltage again.
3. If the battery is weak, charge it fully using a battery charger.
4. If the battery fails the load test, replace it with a new one of the same specifications.

3. Starter Motor Inspection and Replacement

Tools Required: Socket set, torque wrench, screwdriver.
Sub-steps:
1. Disconnect the negative battery terminal again to ensure safety.
2. Locate the starter motor (usually situated near the transmission).
3. Remove any protective covers if necessary.
4. Disconnect the electrical connections from the starter motor, noting their positions.
5. Remove the mounting bolts securing the starter motor.
6. Take out the starter motor and replace it with a new unit if defective.
7. Reinstall the starter motor in reverse order, tightening the bolts to the manufacturer's specifications.
