When you want to jump start one car with your car that is running, it's time to learn how the process works. Start by getting both vehicles nose to nose if possible. If you can't, get the two vehicles as close together as possible. Turn off both vehicles and prepare to connect the jumper cables. 
Jumper cables are marked red and black. The red is the positive cable, while the black is the negative. On the good car, attach the red cable to the red terminal,and the black cable to the black one. Keep apart the two clamps for the dead car, as they are now live from your good battery. 
Attach the cables to the bad battery. Step away from the hood of both vehicles and start the good car. This should give the bad vehicle the charge it needs. When you're ready to give a new (to you) car a try, come on down to our dealership!
