7. Don't let the other end
touch metal. Connect it
to the positive (+)
terminal location of the
vehicle with the
good battery. Use a
remote positive (+)
terminal if the vehicle
has one.
8. Now connect the black
negative (−) cable to
the negative (−)
terminal location of the
vehicle with the
good battery. Use a
remote negative (−)
terminal if the vehicle
has one.
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.
