Tools Required: Multimeter, wire brush (for cleaning terminals).
Check the battery terminals for corrosion; clean if necessary.
Tighten any loose connections.
Reconnect the negative terminal.

3. Testing the Battery

Tools Required: Multimeter.
Measure the voltage of the battery. If below 12.6 volts, charge the battery or replace it if it cannot hold a charge.

4. Jump-Start the Vehicle

Tools Required: Jumper cables.
Connect the jumper cables to a functioning vehicle and attempt to start your Civic.
If the vehicle starts, the battery is likely the issue. Replace it.
