Vehicle Care
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. 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 vehicle with 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. It goes to a heavy,
unpainted metal engine part or
to the remote negative (
−
)
terminal on the vehicle with the
dead battery.
