Here are few tips and instructions on jump starting a dead battery. First things first, though. You need to inspect the dead battery. If you see any damage such as leaks or cracks. DO NOT go any further. Put away the jumper cables and call a wrecker. A damaged battery can explode and really hurt you. If the battery looks ok, then park the cars close enough to each other for the jumper cables to reach and shut off both engines. Now make sure the terminals are not caked with corrosion. Try to clean them off as best you can. A corroded terminal will make it a lot harder to jump the battery. At this point you are ready to hook up your jumper cables to the batteries. (Normally, the red cable is (+) positive and black cable is (-) negative)

They must be connected in this exact order:
1. Connect one end of the (+) positive cable to the (+) positive terminal on the dead battery.
2. Connect the other end of the (+) positive cable to (+) positive terminal on the good battery.
3. Connect one end of the (-) negative cable to (-) negative terminal on the good battery.
4. Connect the other end of the (-) negative cable to the engine block of the dead car.

You are ready to start up the good car
