Solution

1. Preparation

Gather tools: Multimeter, jumper cables, socket set, and flashlight.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

Step 1: Disconnect the negative battery terminal using a socket wrench.
Step 2: Clean any corrosion from the battery terminals using a wire brush or battery terminal cleaner.
Step 3: Reconnect the terminals securely, first the positive and then the negative.

3. Jump-Start Attempt

Step 1: Position a working vehicle close to the G70 and connect the jumper cables: red to red (positive) and black to black (negative).
Step 2: Start the working vehicle and let it run for a few minutes.
Step 3: Attempt to start the G70.

4. Starter Motor Inspection

Step 1: If the vehicle does not start, access the starter motor by removing any components blocking it (such as the intake or engine covers).
Step 2: Disconnect the electrical connector from the starter motor.
Step 3: Use a multimeter to check for voltage at the starter terminal during ignition attempt.
Step 4: If there is no voltage, the issue may lie with the ignition switch or wiring. If voltage is present, replace the starter motor.

5. Final Assembly

Step 1: Reinstall any components removed to access the starter motor.
Step 2: Ensure all connections are tight and secure before closing the hood.
