positive (+) or to a remote positive terminal (+) if
the vehicle has one. Negative (-) will go to a heavy,

negative (-) terminal, if the vehicle has one.
Don't connect positive (+) to negative (-)

you badly. Keep your hands away from moving
parts once the engine is running.

positive (+) cable to the
positive (+) terminal of the
dead battery. Use a
remote positive (+)

has one.

touch metal. Connect it
to the positive (+)
terminal of the good
battery. Use a remote
positive (+) terminal
if the vehicle has one
