Solution

1. Preparation

Gather tools and ensure you have safety gear (gloves, goggles).
Disconnect the negative battery terminal using a wrench.

2. Battery Inspection and Replacement

Inspect Battery:
- Remove the battery cover if applicable.
- Check for corrosion on terminals; clean using a mixture of baking soda and water if necessary.
Replace Battery:
- If the battery voltage is low or the battery is more than 4-5 years old, replace it.
- Disconnect the positive terminal followed by the negative terminal.
- Remove the battery hold-down clamp and lift the battery out.
- Install the new battery by reversing the removal steps (ensure terminals are tightened).

3. Starter Motor Inspection

Remove Starter Motor:
- Disconnect the negative battery terminal again for safety.
- Locate the starter motor, disconnect the electrical connectors, and remove the mounting bolts using a socket set.
- Remove the starter motor from the vehicle.
Test Starter Motor:
- Bench test the starter motor by connecting it directly to a battery.
- If it does not engage or spins slowly, replace it.

4. Reconnect and Verify

Reinstall the starter motor and reconnect all electrical connectors.
Reconnect the battery terminals, starting with the positive terminal followed by the negative terminal.
Ensure all components are secure and properly reconnected.
