3. Connect the negative (-) cable to the negative (-)
terminal of the assisting battery.
4. Make the final connection of the negative (-)
cable. For the 3.0L Vulcan and 3.4L SHO, make the
connection to an exposed metal part of the stalled
vehicle's engine, away from the battery and the
carburetor/fuel injection system. For the 3.0L
Duratec, make the connection to the hood latch of
the disabled engine, away from the battery and the
carburetor/fuel injection system.
The preferred locations of an exposed metal part (to
ground the circuit) are the alternator mounting
brackets or an engine lifting eye. Do not use fuel
lines, engine rocker covers or the intake manifold as
grounding 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.
