Make sure that the jump leads will not
come into contact with the fan, drive-
belts or other moving parts of the
engine.

Start the engine using the booster
battery, then with the engine running at
idle speed, disconnect the jump leads in
the reverse order of connection.

Jump starting will get you out
of trouble, but you must correct
whatever made the battery go
flat in the first place. There are
three possibilities:
1
The battery has been drained by
repeated attempts to start, or by
leaving the lights on.
2
The charging system is not working
properly (alternator drivebelt slack
or broken, alternator wiring fault or
alternator itself faulty).
3
The battery itself is at fault
(electrolyte low, or battery worn out).
Booster battery (jump) starting
When jump-starting a car using a
booster battery, observe the following
precautions:
4 Before connecting the booster
battery, make sure that the ignition is
switched off.
4 Ensure that all electrical equipment
(lights, heater, wipers, etc) is
switched off.
4 Make sure that the booster battery is
the same voltage as the discharged
one in the vehicle.
4 If the battery is being jump-started
from the battery in another vehicle,
the two vehcles MUST NOT TOUCH
each other.
4 Make sure that the transmission is in
neutral (or PARK, in the case of
automatic transmission).
