What does grounded out mean in wiring of automobile?

Answer 1

On an automobile there is no (negative wire), the entire metal frame of the automobile is basically the negative wire. Grounded out means that a positive wire in the system has had the plastic covering somehow torn off and the bare wire is touching a part of the metal on the vehicle or a sharp piece of the vehicles metal has cut into a positive cable, either way it has "grounded out" (Bad thing), not to be confused with just plain "grounded" which is a good thing.
