How to Jump Start a Car?

What You Will Need?

• Another car, in running condition.
• Jumper cables
• You'll also need to park the running car next to the stalled car in such a way that the jumper cables can reach both batteries.

Things to keep in mind before jump-starting the car:

• Turn both keys (working and stalled car) to the OFF position.
• Make sure both batteries have the same required voltage (e.g. 12V)
• Turn off lights, A.C and other electrical loads
• No electrical parts of the two cars should touch each other
• Gear of the vehicle should be in neutral position
• Your vehicle should have same earthed terminal, otherwise, you should follow the instruction provided by the manufacturer and
• Make sure that cables are not ragged or damaged

Once you have taken care of the above points, you should follow the below steps in sequence:

1. On negative grounded system, you need to connect the positive terminal of the battery of your stalled car with the positive terminal of jump-starting battery
2. Then you are advised to connect one end of the other cable to the negative terminal (-) of the jump-starting battery
3. Now connect the second end of the other cable to a section of unpainted metal on the dead car. This can be the engine block or car frame of the vehicle that will be started.
4. Ensure both cables are away from any moving parts of the vehicle (e.g. fan)
5. First, start the car with the good battery, and leave it running. If the battery in the stalled car was really badly drained, it may help to leave them connected for a minute with the good car running before you try to start the dead car. This will allow a little charge to build up in the dead battery.
6. Turn the key in the dead car to start and it should start right up!
7. If your vehicle doesn’t start within 30 seconds, you are advised to call your auto electrician.

Disconnecting the Jumper Cables:

Start removing cables in reverse order (you have to remove the cable, which is connected to engine block or car frame first).

Warning:

If you own a modern vehicle with electronic management system, then you are advised not to jump-start your vehicle without "protected" jump starter leads. For such vehicles, you should follow the owner's handbook for jump-starting procedure.
