Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the battery to prevent accidental short circuits.

2. Battery Inspection

Tools Required: Multimeter, wire brush or battery terminal cleaner
Clean any corrosion from the battery terminals using the wire brush.
Reconnect the battery terminals securely.
Measure the battery voltage; if below 12.4 volts, charge the battery.

3. Jump-Start Procedure

Tools Required: Jumper cables, another vehicle with a functioning battery
Connect the red jumper cable to the positive terminal of the dead battery.
Connect the other end of the red cable to the positive terminal of the good battery.
Connect the black jumper cable to the negative terminal of the good battery.
Attach the other end of the black cable to a grounded metal point on the dead vehicle.
Start the working vehicle and let it run for a few minutes before attempting to start the G70.

4. Starter Motor Testing

Tools Required: Remote starter switch or a jumper wire
Locate the starter motor and disconnect the wiring harness.
Use the remote starter switch to apply power directly to the starter solenoid.
If the starter engages and the engine cranks, the starter motor is functioning.
If it does not engage, replace the starter motor.

5. Fuse Inspection

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box and check the starter relay and ignition fuses.
Replace any blown fuses with the same amperage rating.
