How to “jump start” a car that has a dead battery:
- Position both cars close together so the jump leads will reach both batteries.
- Then connect the car battery booster cables in this order:
- a. Connect (+) positive red cable to the (+) positive terminal on the dead battery.
- b. Connect the other end of the (+) positive red cable to (+) positive terminal on the working car.
- c. Connect (-) negative black cable to (-) negative terminal on the working car.
- d. Connect the other end of the (-) negative cable to the (-) negative terminal on the dead battery.
- You are now ready to start the working car’s engine. Turn off all electrical equipment on the working car (heater, lights, radio, etc.) so that all the battery power is getting used to jump start the dead battery. Let the working car run for a minute or so before you try to start the dead one. Revving the engine in the working car a little bit will produce more current and help with jumping the dead battery.
- Now try and start the dead battery engine by turning the ignition. If it sounds like it is going to start but will not quite go, then rev the working car for a little while longer before trying the dead battery again.
- When the dead battery has started and is running, remove the jump leads.
Do this in reverse order:- a. Disconnect (-) negative black cable from the terminal on dead battery.
- b. Disconnect (-) negative black cable from the (-) negative terminal on the working car.
- c. Disconnect (+) positive red cable from the (+) positive terminal on the working car.
- d. Disconnect (+) positive red cable from the (+) positive terminal on the dead battery.
