    Hey guys, quick question that's been bothering me.

    I understand that you connect the ground of your cars battery to the metal frame of the car to complete the circuit from the battery. But, if you are using the metal frame to allow current flow, why isn't there any current flowing through the metal frame? If there is current flowing, why aren't you shocked just by touching the metal frame if that is what you are using to induce current flow? Thanks guys.

    Because the chassis is only one pole of a battery. You can touch a wire to one side of a battery and nothing will happen. With humans, even if you touch the 12V side no much is going to happen.
