CAUTION:
{
Fans or other moving engine parts can
injure you badly. Keep your hands away
from moving parts once the engine is
running.
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.
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.
6. Connect the red
positive (+) cable to
the positive (+)
terminal of the dead
battery. Use a
remote positive (+)
terminal if the
vehicle has one.
