Draw an equivalent circuit and list the sequence of steps to connect jumper cables properly between two car batteries when trying to jump-start a car with a run-down battery. Be sure to label both the positive and negative terminals on each battery and the red and black cables of the jumper. I t is recommended that the last connection you make should be between the black jumper cable and the run-down car; and instead of connecting it to the negative...
