How to Jump Start a Car With a Jump Starter?
To be honest, you should never try jumping a car of any type yourself (Really you should wait for a trained professional such as a recruit from the AA or RAC etc) because the ECU's are very sensitive, if you try and jump start a car, most likely a fuse will blow in the car and if you are using another car the fuse/ECU will get damaged as well. If the fuse blows you're lucky, it only cost about 59p, however if the ECU becomes damaged in any way, even an error code, they will cost £400+ to repair and £800 to replace, it is also a good idea to see whether you have a dash ECU as well, if you are not sure what an ECU is, it is the cars Electronic Computer Unit, used to control the cars functions such as windows, air conditioning, heated seats, speedometer, most in car features listed just before now are located in the dash ECU if there are two separate and there is another one to control parts in the engine.
1. Read your owner's manual, as it will describe any peculiarities involved in jump-starting your vehicle. Make sure the car actually needs jump starting. If you have tried multiple times to start the car, checked obvious things such as unblocked exhaust, fan-belt is still on, things that would stop the car from starting even if it didn't need "jumping".
2. Pull a car with a charged battery next to the car with the dead battery, situating the two batteries as close together as you can without allowing the two cars to touch.
3. Turn off both engines, pull out the keys, put both cars in park/neutral, engage the emergency brakes and open the hoods.
4. Attach a red-handled/positive jumper cable clamp to the positive terminal (the one with the plus sign) of the vehicle with the charged battery.
5. Connect the other red-handled clamp to the positive terminal of the vehicle with the dead battery.
6. Attach the neighboring black/negative cable to the negative battery terminal of the car with the dead battery. Ground the other black/negative cable on the charging car by clamping it to the bolt where the cable from the negative terminal of the battery attaches to the vehicle chassis, not to the battery itself. Be careful, as a small spark may be produced.
7. Start the engine of the car with the charged battery.
8. Have someone accelerate the engine of the car with the charged battery to a moderate speed and attempt to start the car that has the dead battery. If there is no response, remove the last connection made and re-adjust each of the clamps, particularly those on the dead car; try re-clamping to the terminal or moving the clamp back and forth for a better connection. Reconnect the last cable as in step six and keep trying to start the dead car.
9. Once the dead car is running, remove the clamps one at a time in reverse order. Allow the jump-started car to run for half an hour in order to charge the battery. It will charge whether driving or idling.
