Jump Starting Procedure

Print

  1. Determine voltages of the two batteries; they must be the same.
  2.  
  3. Bring the starting vehicle close (they must not touch) so that the batteries can be reached easily.
  4.  
  5. Turn off all accessories and both engines. Put both vehicles in Neutral or Park and set the parking brake.
  6.  
  7. Cover the cell caps with a rag - do not cover terminals.
  8.  
  9. If the terminals on the run-down battery are heavily corroded, clean them.
  10.  
  11. Identify the positive and negative posts on both batteries and connect the cables in the order shown.
  12.  
  13. Start the engine of the starting vehicle and run it at a moderate speed for a few minutes to allow the dead battery to receive an initial charge. On the dead car, switch on the blower motor to high speed, this should absorb any electrical spike created by the initial, sudden draw of the starter.
  14.  
  15. Try to start the car with the dead battery. Crank it for no more than 10 seconds at a time and let it cool for 20 seconds in between tries.
  16.  
  17. If it doesn't start in 3 tries, there is something else wrong.
  18.  
  19. Disconnect the cables in the reverse order.
  20.  
  21. Replace the cell covers and dispose of the rags.
  22.  


CAUTION
Br very careful to keep the jumper cables away from moving parts (cooling fan, belts, etc.) on both engines.
