Automatic Float Charging
Automatic Float Charging is ideal for maintaining a fully charged battery.
1. Keep the AC power and battery connected after battery is fully charged.
2. The charger monitors the battery and tops it off as needed.
3. The display shows “FLO” when topping off the battery and returns to “FUL” when
completed.
4. To view battery voltage, press the Battery Voltage button.
Note: Charging can be terminated by pressing OFF button at any time.
After AC power interruption, charging restarts at 2 amp rate automatically.
WARNING
If battery size is not known, charge at the 2 amp rate. DO NOT
overcharge batteries.
Alternator Check
Part 1
No Load (Turn OFF all vehicle’s accessories): The battery must be fully charged
before testing the alternator. Run the engine long enough to achieve
normal idle speed and verify there is a no-load voltage.
1. Press Alternator Check to start the check.
2. Alternator Good LED will light to indicate the alternator is good, or
the FAULT LED will light to indicate the alternator may need service.
3. Press Alternator Check again to stop the test.
Part 2
Under Load (Accessories ON): Next, load the alternator by turning on as many
accessories as possible (except for A/C and DEFROST)
1. Press Alternator Check to start the check.
2. Alternator Good LED will light to indicate the alternator is good, or
the FAULT LED will light to indicate the alternator may need service.
3. Press Alternator Check again to stop the test.
If the first alternator check indicates a good alternator and the second indicates the
alternator may need service, the problem could stem from: loose fan belts, an
intermittent diode failure or possibly bad connections between the battery and
alternator and/or ground.
NOTES BATTERY VOLTAGE button is disabled in Alternator Check mode.
The FAULT LED may light because someone has added a number of accessory
loads on the charging system, thereby increasing current demand from the
alternator. MAKE SURE THAT THE ALTERNATOR IS RATED TO SUPPORT THE
APPLICATION.
This check may not be accurate for every make, manufacturer and model of
vehicle.
Check only 12 volt systems.

OPERATING INSTRUCTIONS
Ensure that all installation and operating instructions and safety
precautions are understood and carefully followed by anyone
installing or using the charger. Follow the steps outlined in “Important
Safety Instructions” at the front of this manual.
Charge Rate Selection
After charger clamps are correctly connected, plug in the charger to a 120 volt AC
outlet and the charger will show a circulating pattern on the Digital Display, indicating
power has been applied. Select the proper charge current rate based on battery size.
WARNING
If Digital Display shows “F02” and the Fault indicator lights, the
connection to the battery terminals is bad. Follow the steps outlined in
“Important Safety Instructions” at the front of this manual.
If Rev. Polarity indicator also lights, the RED (POSITIVE) and BLACK
(NEGATIVE) clamps are incorrectly connected to battery terminals.
Follow the steps outlined in “Important Safety Instructions” at the
front of this manual.
Charging the Battery
1. Press 2/6/10 AMP button to begin charging at the 2 amp rate; the unit sounds
a beep and the charging current LED lights. The charger starts charging at 2 amp
rate automatically if 2/6/10 AMP button is not pressed within 3 minutes after
applying AC power.
Charger occasionally sounds a beep and displays “0.0” during self-test or
charging stage changes.
2. Pressing the 2/6/10 AMP button again advances charging rate to 6 amps and
pressing once more advances charging rate to 10 amps. (Pressing the button
again will turn OFF the charger output and the Display will show “000”.) This
selection and actual battery charge rate are monitored by the microprocessor
and the unit will stop charging if the selected rate is too fast or too slow for battery
size or condition.
As the battery nears full charge capacity, the unit’s output will automatically drop
to a lower charge rate.
3. The battery charger displays the charge current. To view the battery voltage,
press BATTERY VOLTAGE button. The charger will sound a beep and display the
battery voltage for 3 seconds, then returns to displaying the charge current.
4. The display shows “FUL” and the Charging Complete LED lights when the battery
is fully charged.
5. Disconnect the AC power cord first, then the NEGATIVE clamp, and finally the
POSITIVE clamp.
