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 qualified technician.
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.

Troubleshooting
DESCRIPTION
REASON/SOLUTION
The battery could be bad. Have it checked or replaced.
The charger will go into desulfation mode. If the
desulfation is not successful after 10 hours, the charger
will go into abort mode.
The battery could not be desulfated; have it checked or
replaced.
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.
The battery is connected backwards. Unplug the charger
and reverse the connections to the battery.
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.
The charger automatically shuts the current off if it
detects the battery may be getting too hot. Have the
battery checked or replaced.
