Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the negative battery terminal to prevent accidental short circuits.

2. Battery Inspection

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Clean any corrosion from the terminals and battery posts with a wire brush and battery cleaner.
3. Reconnect the battery terminals (positive first, then negative).
4. Test the battery voltage again; if below 12.4 volts, consider charging or replacing the battery.

3. Starter Motor Test

Tools Required: Jumper cables
Sub-steps:
1. Locate the starter motor (usually near the bottom of the engine).
2. Use jumper cables to connect the positive terminal of the battery to the starter motor's positive terminal.
3. Ground the negative cable on the engine block or a suitable metal surface.
4. If the starter engages and the engine cranks, the starter is functioning; otherwise, it may need replacement.

4. Ignition System Check

Sub-steps:
1. Locate the ignition switch and disconnect it.
2. Use a multimeter to check for continuity when the key is turned to the start position.
3. If there is no continuity, replace the ignition switch.

5. Final Assembly

Sub-steps:
1. Reassemble any components removed during inspection.
2. Reconnect the battery terminal securely.
3. Ensure all connections are tight and free of corrosion.
