CONNECTING THE BOOSTER CABLES
WARNING For safety reasons:
DO NOT connect the BLACK cable to the negative terminal of the discharged battery - if in doubt, seek qualified assistance.
ENSURE that each connection is securely made and that there is no risk of the clips accidentally slipping or being pulled from the battery terminals - this could cause sparking, which could lead to fire or explosion.
Always adopt the following procedure:
Check that the cables are clear of any moving parts of both engines, then start the engine of the donor vehicle and allow it to idle for a few minutes.
Connect the RED booster cable between the positive (+) terminal of the donor battery and the positive (+) terminal of the discharged battery.
Connect the BLACK booster cable from the negative (-) terminal of the donor battery to a good earth point (e.g. an engine mounting or other unpainted surface) away from the battery and away from fuel and brake lines on the disabled vehicle (lug on alternator casting shown in illustration).
Now start the vehicle with the discharged battery. Once both engines are running normally, allow them to idle for two minutes before switching off the engine of the donor vehicle.
DO NOT switch on any electrical circuits on the previously disabled vehicle until AFTER the booster cables have been removed.
Disconnecting the booster cables must be an EXACT reversal of the procedure used to connect them, i.e: disconnect the BLACK cable from the earth point on the disabled vehicle FIRST.
