Solution

1. Preparation

Ensure the vehicle is in a safe, flat location and the ignition is turned off.
Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery terminals, starting with the negative terminal.
2. Clean the battery terminals and cable connectors with a wire brush.
3. If the battery is faulty, remove it from the battery tray (note the orientation for reinstallation).
4. Replace with a new battery if necessary; ensure it matches the specifications for the G70.
5. Reconnect the terminals, ensuring tight connections and install anti-corrosion washers if available.

3. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor, typically found near the engine's transmission.
2. Disconnect the electrical connections to the starter (note the wiring configuration).
3. Remove the starter motor mounting bolts using a socket set.
4. Inspect the starter for signs of wear or damage; replace if necessary.
5. Reinstall the starter motor and reconnect the electrical connections securely.

4. Final Checks

Sub-steps:
1. Reconnect the negative battery terminal.
2. Start the vehicle to check if the clicking noise persists.
3. If issues remain, consider checking the ignition switch and relay.
