What happens if you put the jumper cables on backwards?

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.

Why don’t you connect the negative when jumping a car?

That’s why it is recommended that you connect the negative jumper cable to the vehicle body and not the negative post of the battery. This is so you can avoid sparks from occurring near the battery where flammable hydrogen gas may be present, resulting in a possible explosion.
