Before you connect the cables, here are
so
me 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 (−)

do not connect the negative (−) cable to the
negative (−) terminal on the dead battery
because this can cause sparks.

grounding point.
