Solution

1. Preparation

Gather tools required: multimeter, socket set, torque wrench, battery terminal cleaner, and safety gloves.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative (-) battery terminal first, followed by the positive (+) terminal.
2. Clean the battery terminals using a battery terminal cleaner to remove any corrosion.
3. Reconnect the positive (+) terminal first, then the negative (-) terminal.

3. Battery Replacement (if needed)

Sub-steps:
1. If the battery voltage is low or the load test fails, remove the old battery by unbolting the battery hold-down and disconnecting the terminals.
2. Install the new battery by connecting the positive terminal first, followed by the negative terminal.
3. Secure the battery with the hold-down bracket.

4. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor (usually near the transmission).
2. Disconnect the wiring harness and the battery cable from the starter.
3. Remove the mounting bolts and take out the starter motor.
4. Inspect the starter for any signs of wear or damage, including the solenoid.
5. If faulty, replace the starter motor with a new one, ensuring all connections are secure.

5. Final Assembly

Sub-steps:
1. Reinstall any components that were removed for access.
2. Ensure all connections are tight and secure.
3. Reconnect the battery terminals.
