To jumpstart a car: Connect red cable to dead battery positive → red cable to good battery positive → black cable to good battery negative → black cable to unpainted metal on dead car (not the battery). Start the working car, wait 3 minutes, then start the dead car. Never connect black to dead battery negative — this risks a spark near battery hydrogen gas.
