Solution

1. Preparation

Gather tools: multimeter, socket set, screwdriver, jumper cables.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative battery cable to ensure safety while working on electrical components.

2. Battery Inspection and Maintenance

Inspect Battery Terminals:
- Clean any corrosion using a wire brush.
- Tighten loose connections to ensure good contact.
Test Battery Voltage:
- Reconnect the negative cable and use a multimeter to measure voltage.
- If below 12.4 volts, proceed to jump-start the vehicle.

3. Jump-Starting the Vehicle

Connect Jumper Cables:
- Connect the positive (+) terminal of the dead battery to the positive terminal of the good battery.
- Connect the negative (-) terminal of the good battery to a ground point on the dead vehicle (not the battery).
Start the Donor Vehicle:
- Let it run for a few minutes before attempting to start the G70.
Start the G70:
- Attempt to start the vehicle. If it starts, allow it to run and check for any abnormal behavior.

4. Starter Motor Inspection

Check Starter Relay:
- Locate the starter relay in the fuse box and swap it with a similar relay to test functionality.
Test Starter Motor Voltage:
- With the ignition in the start position, measure voltage at the starter motor terminal.
- If no voltage is present, the issue may lie in the ignition switch, wiring, or relay.

5. Replace Faulty Components

If the battery is determined to be faulty, replace it with a new one (ensure it meets OEM specifications).
If the starter motor is non-functional, replace it according to manufacturer specifications and torque values.
