Solution

1. Preparation

Tools Required: Socket set, multimeter, wire brush, safety gloves.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Inspect and Clean Battery Connections

Remove the positive terminal followed by the negative terminal from the battery.
Clean the battery terminals and cable ends with a wire brush to remove corrosion.
Reconnect the terminals, ensuring they are tight and secure.

3. Test and Replace the Battery (if necessary)

Use a multimeter to check the battery voltage again.
If the voltage is below 12.6 volts, jump-start the vehicle or replace the battery if it fails to hold a charge.
Ensure the new battery is the correct size and type for the Genesis G70.

4. Check and Test the Starter Motor

Locate the starter motor (usually near the transmission bell housing).
Remove the electrical connectors from the starter.
Use a multimeter to check for voltage at the starter terminals while someone turns the key to the ignition position.
If there is no voltage, further investigate the ignition switch and wiring.

5. Reassemble and Test

Reconnect all components, ensuring all connections are secure.
Reconnect the battery terminals, starting with the positive terminal and followed by the negative.
Attempt to start the vehicle.
