   Open the hood or compartment on each vehicle in which the batteries are located.

2. 2

   Take notation of the positive and negative terminals on each battery. Positive terminals volition be indicated past the plus symbol (+), and negative terminals will be indicated by a minus symbol(-).

3. three

   Connect each finish of the positive jumper cable to the positive terminals on each car battery. The positive jumper cable is unremarkably red in color if it is not labeled otherwise. The order in which you attach the jumper cables does make a difference, then follow this pattern: First connect one end of the positive jumper cable to the dead battery, then connect the other positive end of the jumper cablevision to the charged battery.

4. 

   4

   Connect one stop of the negative jumper cable to the negative terminal on the functional, charged bombardment. In most cases, the negative jumper cablevision is blackness.

5. 

   v

   Attach the other cease of the negative jumper cable to a grounded metal component of the car that contains the dead bombardment. This will ground the car that contains the expressionless battery upon spring-starting. You can attach the basis cable to the frame, chassis, or another component that is reasonably clean and free of pigment or oxidation.

6. 

   half dozen

   Start the engine of the car with the charged battery. Upon starting the engine, its charging arrangement will begin to charge the dead automobile battery through the jumper cables.

7. 

   vii

   Permit at least five minutes to laissez passer after starting the engine of the car with the charged battery. This will let the dead battery to build up a accuse of its own, although it would take longer to fully charge the battery.

8. 8

   Try to start the engine of the motorcar that contains the dead battery. If the jumper cables and the bombardment yous are charging have enough power, the car engine should plow over easily and start.

   • If the engine in the car with the dead battery fails to start, permit v more minutes to pass for the dead battery to charge.

9. 

   ix

   Disconnect and remove the jumper cables from each car later the engine has started in the reverse order in which y'all connected them. This will prevent sparks or an explosion from occurring.

   • Disconnect the grounding cable first, and so the cable attached to the negative terminal on the battery, then the cablevision attached to the positive terminal of the battery of the car that provided the jump, and finally the cable attached to the positive terminal on the previously dead battery.

10. 10

    Allow the automobile which had the expressionless bombardment to continue running for at to the lowest degree another v minutes. This will allow the alternator in the car to recharge the bombardment.
