why is my Genesis G70 making a loud clicking noise when starting

Solution

1. Preparation

• Gather all necessary tools and parts. Ensure the vehicle is parked on a flat surface and the engine is off.
• Tools Required: Socket set, multimeter, jumper wire, battery terminal cleaner.

2. Battery Inspection

• Remove the negative battery terminal using a socket wrench.
• Clean the battery terminals and cable ends with a battery terminal cleaner to remove any corrosion.
• Reconnect the terminal and ensure it is tight.

3. Battery Testing

• Connect a multimeter to the battery terminals (red to positive, black to negative).
• Check the voltage reading; if it is below 12.4 volts, charge or replace the battery as needed.
• If the battery is deemed faulty, replace it with a new one, ensuring proper fit and securing connections.

4. Starter Motor Test

• Locate the starter motor, typically near the transmission.
• Disconnect the electrical connector from the starter.
• Use a jumper wire to connect the positive terminal of the battery directly to the starter motor terminal. If the starter engages and the engine cranks, the starter is functional.

5. Relay and Fuse Check

• Locate the fuse box and identify the starter relay and fuse.
• Remove the starter relay and test it for continuity with a multimeter.
• Replace the relay if it shows no continuity.
• Check the starter fuse for any signs of damage; replace if necessary.
