Jump-start vehicle using jumper cables and a booster battery or auxiliary power supply. (4.6)

Overall Standard (4): Students will inspect, test, and service vehicle batteries.

 Content Understandings

Extending Understandings

Upon successful completion of these tasks students will demonstrate the ability to:

  • Explain why a vehicle may need a jump start.
  • Select the tools required.
  • Describe required safety precautions.
  • Locate the positive terminal on the battery.
  • Locate the negative terminal on the battery.
  • Locate the grounding location on the dead vehicle to use for the black/negative cable.
  • Describe how to connect the jumper cables to two vehicles.
  • Explain the proper order to connect jumper cables to two vehicles.
  • Describe how to disconnect the jumper cables to two vehicles.
  • Explain the proper order to disconnect jumper cables to two vehicles.
  • Hypothesize solutions to possible reasons a vehicle may not start during a jump start procedure.

To move students towards deeper understanding, they should be given opportunities to:

  • Explain why some vehicles should not be jump started.
  • Describe how the portable jump box is used to start a vehicle.
  • Explain the reason to run the vehicle for approximately 30 minutes after it is started from a jump.

Student Reading Guide

How to use jumper cables to jump start a car from another vehicle:

  1. SAFETY CHECKS: 
    • Make sure the battery giving the jump matches the dead battery (12V, 6V, etc).
    • Some newer vehicles should not be jumped due to sensitive circuits – check the owner’s manual.
    • Do not jump frozen, dry, leaking, badly corroded, or visibly damaged batteries.
    • Do not touch the clips of the jumper cables together.  When connected they may cause a spark.
  2. READY CARS: Put both cars in park or neutral, turn the ignitions off, and put on the parking brake.
  3. OPEN THE HOOD of each car. 
  4. ATTACH ALLIGATOR CLIPS to the terminals in the following order: 
    • Red to Dead - Connect red, or positive, clip to the positive terminal on the battery of the dead car. 
    • Red to Donor - Connect the red, positive, clip to the positive terminal on the donor battery on the other car. 
    • Black to Donor - Connect the black clip to the negative terminal of the donor car. 
    • Black to Metal - Connect the black clip to an unpainted metal part of the dead car that is not directly next to the battery. One of the metal struts that hold the hood open is a good place to clip the second black, or negative, clip. 
    • Be sure cables are not in the fan or any hot parts of either vehicle.
  5. START THE DONOR CAR so that the battery can supply power to the dead battery. 
  6. IDLE the donor car, allowing it to run for a few minutes. 
  7. START the dead car.
  8. IF THE CAR DOES NOT START, double check all the connections to be sure they are secure and well connected.  If that does not help, the donor vehicle can be slightly revved to 2000 rpm while starting the dead vehicle.

After the car is jump started: 

  1. Unclip the clips in the reverse order you connected them:
    • The black clip on the unpainted metal of dead car
    • The black clip from the negative terminal of donor car
    • Red clip from the donor car 
    • Red clip from the dead car’s battery
  2. Allow the car to run without stopping for at minimum 20-30 minutes for the alternator to recharge the battery.

 

 

Student Video Guide

  • READY the vehicles: Pull the donor vehicle close to the dead vehicles so the cables will reach.  The vehicles should not be touching. Put both in park or neutral, turn the ignitions off with keys out of ignition, and put on the parking brakes.
  • LOCATE the batteries.  The red terminals are positive and marked with the + symbol.  The black terminals are negative and marked with a – symbol.
  • ATTACH jumper cable alligator clips in the following order:  - Be sure the clips do not touch each other. 
    • Red to Dead - Connect red, or positive, clip to the positive terminal on the battery of the dead vehicle. 
    • Red to Donor - Connect the red, positive, clip to the positive terminal on the donor battery on the donor vehicle. 
    • Black to Donor - Connect the black clip to the negative terminal of the donor vehicle. 
    • Black to Metal - Connect the black clip to an unpainted metal part of the dead vehicle that is not directly next to the battery. One of the metal struts that hold the hood open is a good place to clip the second black, or negative, clip. 
  • START the donor vehicle so that the battery can supply power to the dead battery. 
  • IDLE the donor vehicle, allowing it to run for a few minutes. 
  • START the dead vehicle.
  • Unclip the cables in the reverse order you connected them:
    • The black clip on the unpainted metal of dead vehicle
    • The black clip from the negative terminal of donor vehicle
    • Red clip from the donor vehicle 
    • Red clip from the dead vehicle’s battery
