3. Connect the negative (-) cable to the negative (-) terminal of the
assisting battery.
4. Make the final connection of the negative (-) cable to an exposed
metal part of the stalled vehicle's engine, away from the battery and the

The preferred locations of an exposed metal part (togroundthe circuit)
are the alternator mounting brackets or an engine liftingeye.Do not
use fuel lines, engine rocker covers or the intake manifold asgrounding
points.
Do not connect the end of the second cable to the negative (-)
terminal of the battery to be jumped. A spark may cause an
explosion of the gases that surround the battery.
