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 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
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 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 charge
at the 3A 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.
USING THE ALTERNATOR
PERFORMANCE 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. Start the vehicle and turn on the vehicle's
headlights. Read the voltage on the digital
display. If you get a reading between
13.4 volts and 14.6 volts, the alternator
is working properly. If the reading is less
than 13.4 volts or more than 14.6 volts,
have the charging system checked by a
qualified technician.
