Solution

1. Preparation

Gather tools: multimeter, jumper cables, socket set, wrench, and safety gloves.
Ensure the vehicle is in park (automatic) or neutral (manual) and engage the parking brake.

2. Battery Maintenance

Disconnect the negative (-) battery terminal using a wrench.
Inspect the battery terminals for corrosion; clean them with a wire brush if necessary.
Tighten any loose connections securely before reconnecting the battery terminals.

3. Jump-Start the Vehicle

Connect the jumper cables to the dead battery as follows:
- Red clamp to the positive (+) terminal of the dead battery.
- Red clamp to the positive (+) terminal of the good battery.
- Black clamp to the negative (-) terminal of the good battery.
- Black clamp to an unpainted metal surface on the engine block of the dead vehicle.
Start the engine of the donor vehicle and allow it to run for a few minutes.
Attempt to start the Honda Accord.

4. Starter Inspection

If the vehicle does not start, disconnect the battery again.
Locate the starter motor and remove the electrical connections (note their positions).
Check the starter solenoid for continuity using a multimeter.
Replace the starter if it is found to be defective.
