4.
Connect the jumper cables in the order described below;
•
Connect one red clamp to the positive (+) terminal of the dead battery/disabled vehicle
•
Connect the other red clamp to the positive (+) terminal of the good battery
•
Connect one black clamp to the negative (-) terminal of the good battery
•
Connect the other black clamp to a piece of grounded metal on the dead vehicle, preferably shiny metal (not
painted or oily) that is attached to the engine. Usually a nut, bolt or other protruding shiny metal will work. You
may see a small spark when you connect to a good ground. As a last resort, you may connect to the negative
(-) post of the dead battery, but this risks igniting hydrogen gas coming off the battery
Make sure none of the cables are dangling into the engine compartment, where they could be exposed to moving
parts.
5.
Start the working vehicle. Let it idle for a few minutes. Rev the engine a little above idle for 30 to 60 seconds. You
do this to charge the battery in the dead vehicle. A good clean connection between the battery cables and the
battery terminals is essential
6.
Try to start the disabled vehicle. If it does not start, shut the engine off and disconnect the last connection
temporarily while you slightly twist or wiggle each of the four clamps to help ensure a good electrical connection.
Restart the working vehicle again. Allow another 5 minutes for charging before attempting to start the disabled
vehicle. If this does not work after a few tries, you may need to have the vehicle towed or the battery replaced
7.
Remove the jumper cables once the vehicle starts. Do this in the reverse of the order in which they were attached,
and don't let any of the cables or clamps touch each other (or dangle into the engine compartment)
•
Disconnect the black clamp from the grounded metal on the dead vehicle
•
Disconnect the black clamp from the negative (-) terminal of the good battery
•
Disconnect the red clamp from the positive (+) terminal of the good battery
•
Disconnect the red clamp from the positive (+) terminal of the dead battery
Replace any positive (+) red post protective covers if applicable (You have had to remove or open these in the
beginning) These covers help prevent accidental short circuiting of the battery
8.
Keep the recently-disabled vehicle's engine running. Run the vehicle above idle (slightly revved up with your foot
on the accelerator). This should give the battery enough charge to start the vehicle again. If it does not, you
probably have a dead battery or a dying alternator
Improper jump starting procedures can result in battery explosion and acid burn hazard.
Loosely connected battery cables could damage the electronic control units.
To disconnect battery terminals wait for at least 2 minutes to allow discharge of high voltage or it could lead to
personal injury.
While disconnecting, always disconnect the -VE terminal first and while connecting, always connect the -VE terminal
last.
