3. With the charger plugged in and
connected to the battery and chassis,
press the RATE SELECTION button
until the ENGINE START LED is lit.
4. Crank the engine until it starts or 3
seconds pass. If the engine does not
start, wait 3 minutes before cranking
again. This allows the charger and
battery to cool down.
5. NOTE: During extremely cold weather,
or if the battery is under 2 volts,
charge the battery for 5 minutes
before cranking the engine.
6. If the engine fails to start, charge the
battery for 5 more minutes before
attempting to crank the engine again.
7. After the engine starts, unplug the AC
power cord before disconnecting the
battery clamps 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.
ENGINE STARTING NOTES
During the starting sequence listed above,
the charger is set to one of three states:
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 amps for engine start
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 rdy.
• 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.
• Cool Down – After cranking, the charger
enters a mandatory 3 minute (180
second) cool down state. The digital
display indicates the remaining cool
down time in seconds. It starts at 180
and counts down to 0. After 3 minutes,
the digital display will change from
displaying the countdown to displaying
rdy. 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. Connect the charger to a live grounded
120V AC outlet.
3. If necessary, press the BATTERY TYPE
button until the correct type is indicated.
4. Read the voltage on the digital display.
Keep in mind that this reading is only a
battery voltage reading; a false surface
charge may mislead you. Compare the
reading to the following chart.

TESTER AND CHARGER
When first turned on, the unit operates
only as a tester, not as a charger.
Selecting a charge rate activates the
battery charger and deactivates the tester.
Pressing the RATE SELECTION 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 10 minutes
after the battery charger is first 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 Charging/Maintaining rate
and gel cell battery type.
TESTING AFTER CHARGING
After the unit has been changed from
tester to charger (by selecting a charge
rate), it remains a charger. To change the
battery charger back to a tester, press the
RATE SELECTION button until all charge
rate LEDs are off.
NOTE: The battery tester is only designed
to test batteries. Testing a device with
a rapidly changing voltage could yield
unexpected or inaccurate results.
