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’s engine and charge the dead battery. First of all, shut off all electrical equipment on the good car. (head lights, radio, etc.) Let the good car’s engine run for a minute or so before you attempt to start the dead one. Now get in the dead car and attempt to crank it. If it sounds like it wants to start but won’t quite get there, give it some more time and try again. When the dead has started and is running, it is time to remove the jumper cables. This must be done in reverse order.
Here are the steps: 1.Disconnect (-) negative cable from the engine block on dead car. 2.Disconnect (-) negative cable from the (-) negative terminal on the good battery. 3.Disconnect (+) positive cable from the (+) positive terminal on the good battery. 4.Disconnect (+) positive cable from the (+) positive terminal on the dead battery.
After the dead car has been running for a while, turn it off. See if will start on its own. If it does, you should be ok on the drive home. If not, jump it again and have someone follow you home. When you arrive at home, you can then put a battery charger on it all night and see if it cranks in the morning.
