Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is in a safe and stable position.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Clean Battery Terminals

Remove the battery cables, starting with the negative terminal.
Clean any corrosion from the battery terminals using a wire brush and a mixture of baking soda and water.
Reconnect the terminals securely, ensuring a tight fit.

3. Test and Replace the Battery (if necessary)

Reconnect the battery and use a multimeter to check the voltage.
If the battery voltage is below 12.6 volts, replace the battery with a new one of the same specifications.
Dispose of the old battery properly.

4. Check and Replace the Starter Motor (if necessary)

If the battery is good, inspect the starter motor:
- Remove the starter motor by disconnecting the wiring and unbolting it from the engine.
- Test the starter motor by connecting it directly to a fully charged battery to see if it engages.
- If it does not engage, replace the starter motor with a new unit.
Reinstall the starter motor and reconnect the wiring.

5. Verify Ignition Switch Functionality

If all previous steps are fine, check the ignition switch:
- Remove the steering column covers to access the ignition switch.
- Test the ignition switch using a multimeter to ensure it completes the circuit when turned.
- Replace the ignition switch if it is faulty.
