Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection

Check battery terminals for corrosion.
- Tools Required: Battery terminal cleaner, wire brush.
- Sub-steps:
  1. Clean any corrosion from battery terminals using a wire brush.
  2. Tighten any loose connections securely.

3. Battery Replacement (if necessary)

If the battery voltage is low or the battery is old (over 3-5 years).
- Tools Required: Socket set, torque wrench.
- Sub-steps:
  1. Remove the negative terminal first, followed by the positive terminal.
  2. Remove the battery hold-down bracket and lift the battery out.
  3. Install the new battery in reverse order, ensuring proper alignment and connection.
  4. Torque battery terminals to manufacturer specifications (usually around 10-15 ft-lbs).

4. Starter Motor Inspection

If the battery is good, proceed to check the starter motor.
- Tools Required: Multimeter, jumper cables.
- Sub-steps:
  1. Remove the starter motor from the vehicle.
  2. Test the starter by connecting it directly to the battery using jumper cables to see if it engages.
  3. If the starter does not engage, replace it with a new one.
  4. Reinstall the new starter motor securely.

5. Final Checks

Reconnect the battery terminals and check for proper operation.
- Sub-steps:
  1. Reconnect the negative terminal first, followed by the positive terminal.
  2. Ensure all tools are removed from the engine bay before starting the vehicle.
