Negative pole first: Whole car (except a few parts like the positive pole) are connected. Any mistake with the other lead will lead to a short. If you mess up by touching the car with the other lead nothing will happen.

What happens if you put jumper cables on wrong?

When the jumper cables are incorrectly connected, the polarity of the electrical system on the vehicle with the dead battery will be reversed for a few seconds. This can irreparably damage many of the sensitive electronic components that are common on today’s vehicles, such as on-board computers and electronic sensors.

What should you not do with jumper cables?

The “Don’ts” when jumpstarting a car
