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.
Notice: If you connect a negative cable to the
Engine Control Module (ECM), ECM mounting
bracket or any cables that attach to the ECM
bracket, you may damage the ECM. Attach the
negative cable to a heavy, unpainted metal engine
part, other than the ECM, ECM bracket or cables
attached to the ECM bracket.
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.
