GM Chevrolet Avalanche - Manual (Page 382)

{ 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
basic things you should know. Positive (+) will go to
positive (+) or to a remote positive terminal (+) if
the vehicle has one. Negative (
−
) will go to a heavy,
unpainted metal engine part or to a remote
negative (
−
) terminal if the vehicle has one.
Do not connect positive (+) to negative (
−
) or you
will get a short that would damage the battery
and maybe other parts too.
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.
Your vehicle’s remote negative (
−
) terminal is
marked GND.
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. It goes to a
heavy, unpainted metal engine part or to a remote
negative (
−
) terminal on the vehicle with 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.
The electrical connection is just as good there, and
the chance of sparks getting back to the battery
is much less.
10. Now start the vehicle with the good battery and run
the engine for awhile.
11. Try to start the vehicle that had the dead battery.
If it will not start after a few tries, it probably
needs service.
