battery connections. When the Engine
Start output is enabled the display will
show “rdy”.
4. 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, to allow the
charger and the battery to cool down.
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”.
5. If the engine fails to start, use the
30A Boost rate for 5 more minutes
before attempting to crank the engine
again.
6. After the engine starts, unplug the AC
power cord before disconnecting the
battery clamps from the vehicle.
7. 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.
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. 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 rst 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 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
Boost rate and AGM battery type.
TESTING AFTER CHARGING
After the unit has been changed from
tester to charger (by selecting a desired
rate), it remains a charger. To change the
battery charger back to a tester, press the
Rate Selection button until all 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, rev the engine at
2000 rpm for 30 seconds and turn
on the vehicle’s headlights or other
accessories.
4. 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, refer
to your vehicle’s manual or have the
charging system checked by a qualied
technician.
