NOTE: If you have charged the battery
and it still will not start your car, do not
use the Engine Start feature, or it will
damage the vehicle's electrical system.
Have the battery checked.
1. Set the switch to the OFF position.
2. 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.
3. Plug the charger AC power cord into
the AC outlet.
4. With the charger plugged in and
connected to the battery of the
vehicle, set the ON/OFF switch to
the Engine Start position.
5. Crank the engine until it starts or 5
seconds pass. If the engine does
not start, wait a few minutes before
cranking again. This allows the
charger and battery to cool down.
NOTE: After 3 minutes in Engine Start
mode, the charger will enter into a cool-
down period of 180 seconds. The yellow/
orange Engine Start LED will flash
during the cool down period.
6. If the engine fails to start, use the
40A Boost rate for 5 minutes before
attempting to crank the engine again.
7. After the engine starts, move the switch
to the OFF position and unplug the AC
power cord before disconnecting the
battery clips from the vehicle.
8. Clean and store the charger in a dry
location.
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.

ABORTED CHARGE
If charging cannot be completed normally,
charging will abort. When charging aborts,
the charger's output is shut off and
the Clamps Reversed/Bad Battery
(red) LED will light. Do not continue
attempting to charge this battery. Check
the battery and replace, if necessary.
DESULFATION MODE
Desulfation could take 8 to 10 hours.
If desulfation fails, charging will abort
and the Clamps Reversed/Bad Battery
(red) LED will light.
COMPLETION OF CHARGE
Charge completion is indicated by the
green Charged/Maintaining LED.
When lit, the charger has switched to the
maintain mode of operation.
MAINTAIN MODE
(FLOAT MODE MONITORING)
When the green
LED is lit, the charger has started
maintain mode. In this mode, the
charger keeps the battery fully charged
by delivering a small current when
necessary. If the charger has to provide
its maximum maintain current for a
continuous 12 hour period, it will go into
abort mode (see Aborted Charge section).
This is usually caused by a drain on the
battery or the battery could be bad. Make
sure there are no loads on the battery. If
there are, remove them. If there are none,
have the battery checked or replaced.
MAINTAINING A BATTERY
The SC1324 charges and maintains
12 volt batteries, keeping them at full
charge.
NOTE: The maintain mode technology
allows you to safely charge and maintain
a healthy battery for extended periods of
time. However, problems with the battery,
electrical problems in the vehicle, improper
connections or other unanticipated
conditions could cause excessive current
draws. As such, occasionally monitoring your
battery and the charging process is required.
FAN OPERATION
It is normal for the fan to be on all the
time. Keep the area near the charger
clear of obstructions to allow the fan to
operate efficiently.
