surges. Turn all other accessories off.

do not touch one another.

any unnecessary electrical
equipment.

of the discharged battery (1) to the
positive (+) terminal of the booster
battery (2).
4. Connect one end of the second
lead to the negative (-) terminal of
the booster battery (3) and the
other end to a metal part of the
engine to be started (4), not to the
negative (-) terminal of the discharged battery.
5. Make sure that the jump leads are clear of moving parts of the engine.
Do not connect the end of the second cable to the negative (-)
terminal of the battery to be jumped. A spark may cause an
