6. 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.

positive (+) terminal if the
vehicle has one.
9. 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.
