Solution

1. Preparation

Ensure the vehicle is in park and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shock.
Gather necessary tools.

2. Battery Inspection

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Clean any corrosion from the terminals using a wire brush and a mixture of baking soda and water.
3. Reattach the terminals securely (positive first, then negative).
Tools Required: Wire brush, baking soda, wrench set.

3. Starter Motor Testing

Sub-steps:
1. Locate the starter motor, typically found near the bottom of the engine near the transmission.
2. Disconnect the electrical connector from the starter.
3. Using a jumper wire, connect the battery positive to the starter terminal and the negative to the starter case.
4. If the starter engages and the engine cranks, the starter is likely faulty.
Tools Required: Jumper wire, wrench set.

4. Replace Battery or Starter (if necessary)

Sub-steps:
1. If the battery is dead, replace it with a new one of the same specifications.
2. If the starter is defective, remove the mounting bolts and disconnect the electrical connectors.
3. Install the new starter in reverse order of removal, ensuring all connections are tight.
Tools Required: Socket set, torque wrench, screwdriver set.
