OK before you go of on me about this, i have done research with highschool kids from three different schools, and i have found that most of them do not know how to connect jumper cables propperly.
First: Connect the red clamp to the positive terminal on the dead battery
Second: Connect the other red clamp to the positive terminal on the live battery
Third: Connect the black clamp to the negative terminal on the live battery
Fourth: this is the most important step and most forgotten, You need to attach the other black clamp to a ground on either the engine or the frame, most late model cars now have a ground point that is labeled underneath the hood.
You do this to prevent an explosion, when you attach the last connection there will be a spark and if your battery is leaking hydrogen gas the gas can explode, causing injury and maybe death.
I hope that this will inform many because the lack of knowledge most have about their cars nowadays, to me is quite sad and appaling. |

cool, I know next to nothing about cars. What battery are you actually jump starting here? I presume theirs? but I may be wrong.

you are jumping either yours or theirs it doesnt really matter as long as you start with the dead battery |

It says this in most cars that I’ve jumped. |

Common knowledge.
3* for trying |

It’s easier to remember the sequence if you know why it’s necessary to follow the sequence. Specifically:
1. The ends of the cables will tend to bump into each other.
2. The ends of the cables will brush against the body of the car.
So, you first connect a cable to the positive terminal of the "dead" battery. If the ends of the cables bump into each other at either end, the circuit does not complete, and nothing happens. Similarly, if any cables should touch the body of either car, they become grounded to the negative terminal, and with no complete circuit, nothing happens.
Second, you connect the other end of the positive cable to the positive terminal of the "live" battery. Now, you only have the negative cable to contend with. It may bump into the chassis of either car, but the circuit isn’t complete, so everything’s fine at this point.
Third, connect the negative cable to the negative terminal on the "live" battery. The other end may dangle and touch the other car’s chassis, but, so long as it’s not on the positive terminal, nothing happens.
Last, connect the negative cable to the chassis of the car with the "dead" battery. Now, you’ll probably get a spark, which is why it’s important to connect it away from the battery.
The point of the sequence is to prevent sparks or short circuits in the event the cables touch anything they shouldn’t. |

Also, there is a risk of explosion. The dead battery will be putting off a lot of flammable fumes, and when you connect that last clamp, there will be a spark. You connect to a piece of metal away from the battery so the spark won’t ignite the fumes. |
