Solution

1. Preparation

Gather tools and ensure the vehicle is in a safe location.
Tools Required: Multimeter, socket set, jumper cables, wrench set, safety gloves.
Safety Warnings: Disconnect the battery before working on electrical components.

2. Battery Inspection

Remove the negative (-) terminal from the battery using a wrench.
Inspect the terminals for corrosion; clean with a wire brush if necessary.
Reconnect the negative terminal securely.

3. Jump-Start Procedure

Connect jumper cables to the dead battery: positive (+) to positive (+) and negative (-) to ground (any unpainted metal part) on the vehicle with the dead battery.
Start the functioning vehicle and let it charge for a few minutes.
Attempt to start the Genesis G70.

4. Starter Motor Testing

If the vehicle still does not start, access the starter motor.
Disconnect the wiring harness and use a multimeter to check for voltage at the starter terminals while a helper turns the key to the start position.
If voltage is present, replace the starter motor.
If no voltage is present, further investigate the ignition switch or wiring.

5. Final Assembly

Reassemble all components, ensuring all electrical connections are secure.
Reconnect the battery and ensure everything is functioning properly.
