Connecting the jumper cables
Note: In the illustration, the vehicle on the bottom is used to designate
the assisting (boosting) battery.
1. Connect the positive (+) jumper
cable to the positive (+) terminal of
the discharged battery.
2. Connect the other end of the
positive (+) cable to the positive
(+) terminal of the assisting battery.
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 carburetor/fuel injection system.
Note: Do not attach the negative (-) cable to fuel lines, engine rocker
covers, the intake manifold or electrical components as grounding points.
WARNING: Do not connect the end of the second cable to the
negative (-) terminal of the battery to be jumped. A spark may
