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.

cable to the negative ( )
terminal of the good battery.
Use a remote negative ( )
