What is "Ground" in automotive terms? No general answers please :-)?

Please, Don't say it the the "chassis" or "frame of the car or engine because I know that. There all linked 2gather. But what is ground?





Is it a common link in a circuit or something along those lines, I was told? I thought "Ground" was basically any conductor connected to the battery's negative side, for example the battery negative terminal is connected to the cars "chassis" or 'frame" basically the "chassis" or "frame" would be considered ground because its metal frame acts as a conductor to negative side of the battery. The"Engine" is connected to the frame also, that's a ground also. But I'm told i was incorrect.|||Sometimes to "ground" something, is basically to drain its energy. If it is near something with a live current, grounding it relieves it from being a threat.|||You are correct.|||You're correct. Ground is basically anything that provides a path back to the negative polarity of the battery in order to make the electrical circuit complete.
