Sorry if I am not being clear. I am talking about the cables that lead from your battery to your car, not the jumper cables.
Your positive cable is red and connects your battery to your starter motor and other electrical equipment.
Your negative cable is black and it connects you battery to a ground point on your car’s engine or chassis.
I assummed in your original post that you were asking about the battery connection to your car.
If you are asking about getting the jumper connections to stay attached that is just a matter of getting them to clamp on.
Avatar didn’t come out of nowhere at all. It is made by one of the most beloved and successful film makers in history. The hype leading up to that movie was off the charts.
