Saturn 2009 ASTRA - Manual (Page 255)

{ CAUTION
Fans or other moving engine
parts can injure you badly. Keep
your hands away from moving
parts once the engine is running.
5. Check that the jumper cables
do not have loose or missing
insulation. If they do, you could
get a shock. The vehicles
could be damaged too.
Before you connect the cables,
here are some things you to
know. Positive (+) will go
to positive (+) or to a remote
positive (+) terminal if the vehicle
has one. Negative (
−
) will go
to the engine lift hook.
Do not connect positive (+) to
negative (
−
) or you will get
a short that would damage the
battery and maybe other
parts too. And do not connect
the negative (
− ) cable to
the negative (
−
) terminal on the
dead battery because this
can cause sparks.
6. Connect the red positive (+)
cable to the positive (+) terminal
of the dead battery. Use a
remote positive (+) terminal if
the vehicle has one.
7. Do not let the other end touch
metal. Connect it to the
positive (+) terminal of the
good battery. Use a remote
positive (+) terminal if the
vehicle has one.
8. Now connect the black
negative ( − ) cable to the
negative ( − ) terminal of the
good battery. Use a remote
negative (
− ) terminal if the
vehicle has one.
Do not let the other end touch
anything until the next step.
The other end of the negative (
− )
cable does not go to the dead
battery.
9. Connect the other end of the
negative (
−
) cable at least
18 inches (45 cm) away from
the dead battery, but not
near engine parts that move.
Connect it to the engine lift hook.
You may need to scrape the
surface with your jumper cable
to obtain a proper ground.
The electrical connection is just
as good there, and the chance
of sparks getting back to the
battery is much less.
