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 four states:
• Wait for ready – The charger charges the
battery for 2 minutes before the Wait for
Cranking state. While waiting for ready, the
digital display shows On and the engine
can be cranked. For severely discharged
batteries, it is not recommended to crank
during this time.
• Wait for cranking – The charger waits
until the engine is actually being cranked
before delivering the amps for engine
start. 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 7 seconds.
• Cool Down – After repeated cranking
during a 3-minute ready period, 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. After 2 hours of Engine Starting,
the unit will automatically reset to Tester
mode, just as if the STOP button had
been pressed.
TESTER AND CHARGER MODES
When rst powered up, the unit operates
only as a TESTER, not as a charger.
Pressing the START/STOP button
deactivates the tester mode and activates
the CHARGER mode. Pressing the START/
STOP button again will shut-off the charger
mode and activate the TESTER mode.
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 sections 6 and 7.
2. Connect the charger to a live grounded
120V AC outlet.
3. If necessary, press the BATTERY
TYPE button until the correct battery
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.
6V Battery

Less than 6.1 Less than 12.2 Discharged
NOTE: The battery tester is only designed
to test batteries. Testing a device with
a rapidly changing voltage could yield
unexpected or inaccurate results.
POWER-UP AUTO-START
When charger is rst powered up, if
START button is not pressed within
30 seconds, but a battery is properly
connected, the unit will automatically
switch from TESTER mode to CHARGER
mode. In that case, unit will set the battery
type to AGM, and the RATE to BOOST.
Use RATE SELECTION and BATTERY
TYPE buttons to change these settings.
See Section 10.
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. Connect the charger to a live grounded
120V 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, have the charging system
checked by a qualied technician.
