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. Don't 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.
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 engine part or to a remote
negative (−) terminal on the vehicle with the
dead battery.
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.
