Solution

1. Preparation

Tools Required:
- Multimeter
- Socket set
- Jumper cables
- Wire brush (for cleaning terminals)
Safety Warnings:
- Disconnect the battery before working on electrical components.

2. Battery Inspection

Clean Battery Terminals:
- Use a wire brush to clean any corrosion from the positive and negative terminals.
- Ensure tight connections by securing the terminal clamps firmly.
Test Battery Voltage:
- Use a multimeter to measure the battery voltage. If it’s below 12.4 volts, charge the battery or replace it.

3. Jump-Starting the Vehicle

Connect Jumper Cables:
- Connect the positive (red) cable to the dead battery's positive terminal.
- Connect the other end of the positive cable to the positive terminal of the working battery.
- Connect the negative (black) cable to the working battery's negative terminal.
- Connect the other end of the negative cable to a grounded metal surface on the vehicle with the dead battery.
Start the Vehicle:
- Attempt to start the vehicle. If it starts, the battery may need replacing.

4. Starter Motor Testing

Access the Starter Motor:
- Remove any necessary components to reach the starter motor.
Check Voltage at the Starter Solenoid:
- Use a multimeter to check for voltage at the solenoid while attempting to start the car.
- If there is no voltage, further investigate wiring and ignition switch.

5. Fuse Inspection

Locate the Fuse Box:
- Refer to the owner's manual to find the location of the fuse box.
Inspect Fuses:
- Check the fuses related to the starting system (refer to the diagram on the fuse box cover) and replace any that are blown.
