In Jumper Cables Is Red Positive?

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.

Does the red or black jumper cable go first?

Attach the red jumper cables first. Start by clamping one red cable to the positive side of the battery that won't start. Then attach the other red clamp to the positive side of the working battery. Next, clamp one black cable to the negative side of the working battery.

What color is the positive cable on jumper cables?

FYI, the wire running from the car to the positive terminal is red; the wire to the negative terminal is black. The jumper cable's clamps are color coded in red and black as well, so it's easy to know what goes where as you get set for the jump-start.
