ground connection

Whenever a car has some electrical problems, you often hear about a ground connection or 'ground'. Modern cars have a 12-volt electrical system where the positive battery terminal (+12V or 'power') is distributed through wiring and fuses, while the battery negative "-" terminal is connected to the car's body ('ground'); thus a car body acts as a conductor.
