Solution

1. Preparation

Tools Required: Multi-meter, socket set, screwdrivers, jumper cables.
Safety Warnings: Disconnect the battery before starting any electrical work.

2. Battery Inspection and Replacement

Check Battery Voltage:
- Use a multimeter to measure the battery voltage.
- If the voltage is below 12.4V, charge or replace the battery.
Inspect Battery Connections:
- Remove the negative terminal (black) first, then the positive terminal (red).
- Clean any corrosion from the terminals using a wire brush.
- Reconnect terminals securely, starting with the positive terminal.

3. Starter Motor Testing

Remove Starter Motor:
- Disconnect the battery again for safety.
- Remove any components obstructing access to the starter motor.
- Unbolt the starter from the engine block using a socket set.
Test Starter Motor:
- Apply direct battery voltage to the starter motor terminals using jumper cables.
- If the starter engages and spins, it is functional. If not, replace it.

4. Ignition Switch and Wiring

Inspect Wiring:
- Check the wiring harness connected to the ignition switch for any signs of damage.
- Ensure all connectors are tightly secured.
Test Ignition Switch:
- Remove the ignition switch from the steering column.
- Use a multimeter to check for continuity between terminals when the key is turned to the start position.
