POWER-UP AUTO-START
When charger is first 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 qualified technician.
NOTE: Refer to your vehicle owner’s manual for appropriate voltage numbers for your alternator.
12. MAINTENANCE AND CARE
A minimal amount of care can keep your battery charger working properly for years.
• Clean the clamps each time you are finished charging. Wipe off any battery fluid that may have come
in contact with the clamps to prevent corrosion.
• Occasionally cleaning the case of the charger with a soft cloth will keep the finish shiny and help
prevent corrosion.
• Coil the input and output cords neatly when storing the charger. This will help prevent accidental damage
to the cords and charger.
• Store the charger unplugged from the AC power outlet in an upright position.
• Store inside, in a cool, dry place. Do not store the clamps clipped together, on or around metal, or
clipped to the cables.
13. TROUBLESHOOTING AND ERROR CODES
Error Codes
CODE DESCRIPTION REASON/SOLUTION
F01
The battery voltage is still under 10V
(for a 12V battery) or 5V (for a 6V
battery) after 2 hours of charging.
The battery could be bad. Have it checked or replaced.
F02
The charger cannot desulfate the
battery.
The battery could not be desulfated; have it checked or
replaced.
F03
The battery was unable to reach the
“full charge” voltage.
May be caused by trying to charge a large battery or bank of
batteries on too low of a current setting. Try again with a higher
current setting or have the battery checked or replaced.
F04
The connections to the battery are
reversed.
The battery is connected backwards. Unplug the charger and
reverse the connections to the battery.
F05
The charger was unable to keep
the battery fully charged in maintain
mode.
The battery won’t hold a charge. May be caused by a drain on
the battery or the battery could be bad. Make sure there are
no loads on the battery. If there are, remove them. If there are
none, have the battery checked or replaced.
F06
The charger detected that the
battery may be getting too hot
(thermal runaway).
The charger automatically shuts the current off if it detects
the battery may be getting too hot. Have the battery
checked or replaced.
If you get an error code, check the connections and settings and/or replace the battery.
