Start a dead battery by jump-starting it with another vehicle. First, connect the positive (red) jumper cable to the positive terminal of the dead battery and the positive terminal of the good battery. Then, connect the negative (black) cable to the negative terminal of the good battery and an unpainted metal surface on the dead car. Start the working vehicle first, then try starting the dead car. Once it runs, remove the cables in reverse order.
