Operating instructions

• 8 •
1. With the charger unplugged from the
AC outlet, connect the charger to the
battery, following the instructions given
in the CHARGING A BATTERY IN
THE VEHICLE section.
2. With the charger plugged in and
connected to the battery of the vehicle,
press the BATTERY SIZE button until
the ENGINE START LED is lit. The
display mode will be automatically set to
VOLTAGE.
3. Crank the engine until it starts or 3
seconds pass. If the engine does not
start, wait 3 minutes before cranking
again. NOTE: During extremely cold
weather, or if the battery is under 2
volts, charge the battery for 5 minutes
before cranking the engine.
4. If the engine fails to start, charge the
battery for 5 more minutes before
attempting to crank the engine again.
5. After the engine starts, unplug the AC
power cord before disconnecting the
battery clamps from the vehicle.
NOTE: If the engine does turn over but
never starts, there is not a problem with
the starting system; there is a problem
somewhere else with the vehicle.
STOP cranking the engine until the
other problem has been diagnosed and
corrected.
ENGINE STARTING NOTES
During the starting sequence listed above,
the charger is set to one of three states.
Wait for cranking – The charger waits until
the engine is actually being cranked before
delivering the additional amps for engine
start. The charger delivers charge at a rate
of up to 10 amps (12 amps for SC-10030A)
while waiting and will reset if the engine
is not cranked within 15 minutes. (If the
charger resets, it sets itself to the default
start up settings). While waiting for cranking,
the digital display shows the battery voltage
(it cannot be set to percent).
Cranking – When cranking is detected,
the charger will automatically deliver up
to its maximum output as required by
the starting system for up to 3 seconds
or until the engine cranking stops. The
digital display shows a countdown of the
remaining crank time, in seconds.
Cool Down – After cranking, the charger
enters a mandatory 3 minute (180 second)
cool down state. During this period, no
settings can be changed. The buttons are
ignored. The digital display indicates the
remaining cool down time in seconds. It
starts at 180 and counts down to 0. The
ENGINE START LED blinks once every
second. During the cool down period, no
current is delivered to the battery. After
3 minutes, the ENGINE START LED will
stop blinking and will light continuously,
indicating that another crank cycle can
be started. The digital display will change
from displaying the countdown back
to displaying the battery voltage. The
CHARGING LED will then be lit.
USING THE BATTERY VOLTAGE
TESTER
1. With the charger unplugged from the
AC outlet, connect the charger to the
battery, following the instructions given
in previous sections.
2. Plug the charger AC power cord into
the AC outlet.
3. If necessary, press the BATTERY TYPE
button until the correct type is selected.
4. Read the voltage on the digital display
or press the Display Mode button to set
the tester to BATTERY %, to read the
voltage as a percent of charge. Keep in
mind that this reading is only a battery
voltage reading; a false surface
charge may mislead you. Compare the
voltage reading to the following chart.

TESTER AND CHARGER
When rst turned on, the unit operates only
as a tester, not as a charger. To continue
to use it only as a tester, avoid pressing
the BATTERY SIZE button. Selecting a
charge rate activates the battery charger
and deactivates the tester. Pressing the
BATTERY SIZE button when the ENGINE
START LED is lit (except during the 180
second cool down) will shut off the charger
and activate the tester.
POWER-UP IDLE TIME LIMIT
If no button is pressed within 15 minutes
after the battery charger is rst powered
up, the charger will automatically switch
from tester to charger if a battery is
connected. In that case, the charger will
be set to the start-up default settings.
