Solution

1. Preparation

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

2. Battery Terminal Inspection

Sub-steps:
1. Remove the positive (+) and negative (-) battery terminals.
2. Clean any corrosion on the terminals and battery posts with a wire brush and a mixture of baking soda and water.
3. Reattach the terminals securely, ensuring a tight fit.

3. Battery Replacement (if necessary)

Sub-steps:
1. If the battery voltage is low or the load test fails, remove the old battery from the vehicle.
2. Install a new battery with the same specifications (e.g., CCA rating).
3. Connect the positive terminal first, followed by the negative terminal.

4. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor (typically near the transmission).
2. Disconnect the wiring harness from the starter motor.
3. Check for any damage or wear on the starter motor and its connections.
4. If damaged, remove the starter motor using a socket set and replace it with a new unit.
