than regular batteries.
BOOST CHARGING
Boost charging is used to rapidly charge a
battery, usually prior to attempting to start
the engine in a flat battery situation.
Boost charging should be avoided on
small & deep cycle batteries. Do not
overcharge in the boost charge position –
recommended charge period is 5 minutes,
followed by a rest period of 15 minutes
before further charging. Do not leave the
charger unattended during boost charge.
NOTE: The Hi/ Lo switch is bypassed
when Boost/ Start is selected.
ENGINE STARTING
This charger, together with the vehicle's
own flat battery, can deliver starting
currents in excess of 100 Amps for several
seconds, long enough to crank and start
the engine.
It is necessary to charge the battery for
a few minutes, using the Boost-charge
setting, before attempting to start the
engine. The benefit of this brief charge is
firstly that, when starting is attempted, all
the current from the charger goes to the
starter and not to the battery, and secondly
that this brief period of charging will enable
the battery to contribute to the starting
current.
Method
Make sure that all loads on the battery
are switched off and always observe the
correct polarity of connections, red to
positive (+), and black to negative (-).
Connect the ground connection to the
engine or chassis away from fuel lines
and battery vents.
1. Switch to 'Boost/ Start', turn the main
supply on, and allow the battery to
charge until the green and yellow
indicators begin to flash alternatively.
Do not leave in the Boost/ Start
mode for longer than 15 minutes
(refer to 'Boost Charging' section for
instructions).
2. Operate the starter with the charger
still on 'Boost/ Start'. The engine
should start or briskly crank for several
seconds before the charger's internal
cut-out operates.
3. If the engine cranks, the charger's
internal cut-out comes into operation.
If the engine does not start after two or
three attempts, wait for a further period
of at least 5 minutes with the charger
on 'Boost/ Start' charge, and try again.
Note: If the starter operates well but
the engine does not start, identify the
reason and correct the fault (check fuel
and ignition).
4. If the engine does not crank, and after
a few seconds the charger's internal
cut-out comes into operation, then this
is an indication that either the initial
charging period of the battery was not
long enough (allow a further period of
Boost-charge), the battery is very faulty,
the connections between the battery
and the battery connectors are faulty, or
that the starter motor is jammed.
5. If the engine does not crank, and the
charger's internal cut-out does not
operate within a few seconds, then this
is an indication of a fault in the starting
system of the car. Check for a faulty
starter motor, solenoid, earth strap from
battery to car bodywork, earth strap
from engine to car.
OVERLOAD PROTECTION
The automatic feature of the charger
prevents batteries from being damaged
by overcharging and provides protection
for the charger against short-circuits and
reversed polarity connections.
There is a self-resetting thermal overload
in the input circuit and a self-resetting
overload in the output circuit.
