Connect one red clamp to the positive (+) battery post of the “dead” battery. Connect the other red clamp to the positive (+) post of the good battery. Connect one black-end clamp to the negative (-) post of the good battery.

Why do you connect positive to positive when jumping a car?

Connect positive first, negative having less potential won’t arc. The higher the voltage, the greater the chance of arcing and fusion. On a car if negative first and you are touching any metal part of car, when attaching positive there is possibility of arcing through you. Your body becomes part of the circuit.
