Solution

1. Preparation

Tools Required: Multimeter, socket set, screwdriver set, wire brush, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Battery Inspection and Service

Sub-steps:
1. Disconnect the negative (-) battery terminal using a socket wrench.
2. Inspect the positive (+) and negative (-) terminals for corrosion. Clean with a wire brush if necessary.
3. Reconnect the negative terminal securely.

3. Fuse Inspection

Sub-steps:
1. Locate the fuse box, usually found under the dashboard or in the engine compartment.
2. Remove the cover and check the starter-related fuses for continuity using a multimeter.
3. Replace any blown fuses with the same amp rating.

4. Starter Motor Testing

Sub-steps:
1. Locate the starter motor, typically near the engine block.
2. Disconnect the wiring harness and the power cable from the starter.
3. Use a multimeter to check for voltage at the starter terminal when the ignition key is turned to "Start."
4. If no voltage is present, further investigate the ignition switch and wiring.
5. If voltage is present but the starter does not operate, replace the starter motor.

5. Ignition Switch Testing

Sub-steps:
1. Remove the steering column cover to access the ignition switch.
2. Use a multimeter to check for continuity at the ignition switch when the key is turned to the "Start" position.
3. Replace the ignition switch if it fails the continuity test.
