Chevrolet 2003 Venture Owner's Manual page 379

Don't let the other end touch anything until the next
step. The other end of the negative (-) cable
doesn't go to the dead battery. It goes to a heavy,
unpainted metal 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 a while.
11. Try to start the vehicle that had the dead battery. If
it won't start after a few tries, it probably needs
service.
Notice: Damage to your vehicle may result from
electrical shorting if jumper cables are removed
incorrectly. To prevent electrical shorting, take care
that the cables don't touch each other or any
other metal. The repairs wouldn't be covered by
your warranty.
