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.
Don't connect positive (+) to negative ( ), or you'll
get a short that would damage the battery and
maybe other parts, too. And don't 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 location on the vehicle with the dead battery.
Use a remote positive (+) terminal if the vehicle
has one.
