7 Easy Steps to Jump Start a Car

 

1) Open Cars’ Hoods and Locate the Batteries

 

First of all, open the hood of the dead battery car and locate where the battery is;

  • In some vehicles, the battery is at the front.
    • In some vehicles, the battery is between the engine and the passenger side area.
  • In some cars, the battery is not under the hood but at the car’s rear.
  • In some rare vehicles, the battery is completely hidden under the engine, but it has (+) and (-) terminal areas at the top separately; locate them.

 

When you finish the dead battery car, do the same with the working battery car.

 

2) Park the Cars adjacent to each other

 

If you have big jumper wires, then you can park the vehicles in any position, but if the wires are small, then you need to park them adjacent to each other according to batteries position;

  • If the batteries are at the front, then park cars in front of each other with a distance of feet or two between them.
  • If the batteries are at the end of the car engine area,  you may park the cars next to each other however you want, as long as jumper wires reach both batteries.

! ! ! Precautions to follow ! ! ! 

 

! Turn the wheels away from the public.

! Never allow any part of the cars to touch each other

! Park the cars in a flat, open area away from the public and make sure all brakes are on.

 

3) Prepare Cars for a safe Jumpstarting

 

You need to do the following inspections and preparations before trying to jumpstart any car;

    • Wear safety gloves + Goggles ( if you have any ).
    • Switch off both cars and all their electrical components like radio, AC, LCD, lights, etc. 
  • Check for terminals; if they are loose, tighten them up. If the terminal is still loosened after full tightening, use a tin can shred or a wire to fill the area and then tighten it again. 
  • Inspect batteries for leaks or damages; if there are, don’t try to jump-start them, or they may end in a fire or explosion. In this case, call for the repair shop or replace the battery.
  • Remove the positive protective covers from both batteries.
  • If the terminals are too dirty, remove them, clean them up, even brush them with some wire brush, and then tighten them again. Only do this if your car has suffered a total power failure.

 

4) Connect the Jumper Cables

 

Now, get your jumper cables out and untangle them properly because if any part of their covering is damaged along their length, a spark & fire may occur. Then, carefully connect the wires exactly as described below;

Step no 1) Get the red/positive wire and connect it with the dead battery’s positive terminal (+).

Step no 2) Now, connect the other end of the same red wire with the working battery’s positive (+) terminal.

Step no 3) Get the black/negative wire and connect it with the working battery’s negative terminal (-).

Step no 4) Finally, connect the other end of the negative wire/black wire with any metal part of the engine area. Don’t connect the wire to the negative terminal of the dead battery because the dead battery emits hydrogen gas, which can cause a huge explosion even with a small spark.

 

! ! ! Precautions to follow ! ! ! 

 

!  Ensure that no wires hang in the engine area, where they may get entangled with the moving parts.

!  Make sure the clamps never touch any other area of the car or each other, which may cause a spark or even fire.

!  Connect clamps firmly with terminals, bolts, nuts, and other protruding areas so they don’t slip by chance and cause a spark.

 

5) Charge the Dead Battery and Start the Car

 

Now, switch on the engine of the working battery car and stay idle for 30 ~ 60 seconds so it will charge the dead battery a bit and only then try to start the dead car.

If the dead battery car doesn’t start, disconnect the last negative wire connection, which you have made with the metal part, then wriggle the other 3 clamps to ensure secure connections. Then, let the dead battery get charged up for another 5 minutes and start the dead car again.

If the car starts well and is good. If it doesn’t, you need to get it to a repair shop or get a new battery for your car. 

 

6) Unclamp the Cables

 

After the car starts, unclamping the jumper cables is as necessary as clamping them because one wrong move clamp may touch a sensitive area, causing a spark that may end up in a fire or explosion.

Unclamp the jumper cables exactly in the opposite way of clamping them, such as;

Step no 1) First, unclamp the negative wire from the metal part of the dead battery car.

Step no 2) Second, unclamp the negative wire from the negative ( – ) terminal of the working/boost battery.

Step no 3) Third, unclamp the positive clamp from the positive ( + ) terminal of the working/boost battery.

Step no 4) Lastly, unclamp the positive wire from the dead battery’s positive terminal.

 

Then roll the wires, clean them if dirty, and store them in a cool, shady place away from moisture.

 

! ! ! Precautions to follow ! ! ! 

 

!  Ensure that no wire falls in the engine area, which may get stuck.

!  Make sure that no wire/clamps touch each other or any other car areas during clamping.

7) Keep the Engine on of the dead Car

 

When the dead battery car starts up, don’t let it off. Keep the engine running for 20 ~ 30 minutes for the battery to get charged. That’s it. It is important to understand that you can jumpstart without another car using an external power bank, which is very costly. If you don’t have cables, a power bank, or another car, it’s best to call the jump start service helpline.
