One is marked positive (+), the other negative (-). There are also positive and negative cables in the jumper cable set. The red one is positive (+), the black one is negative (-). Never connect the red cable to the negative battery terminal or a vehicle with a dead battery.In the world of DC electronics, the accepted wiring convention is that the red wire carries the positive voltage, and the black is circuit ground. Usually the red is marked as + (plus) and the black is marked as – (minus). Notice that in both AC electricity and DC electronics, there is a black wire.The coloring is as follows: The positive current must be red. The negative current must be black. The ground wire, if present, must be white or grey.
