• The CHARGED (green) LED will light if a charged battery is tested.
• The CHARGING (yellow) LED does not light in the Battery Test Mode.
• The CONNECTED (yellow) LED will light if a properly connected bat-
tery is detected.
Initial Percent Calculation: When a battery % is calculated for the first
time after connecting a battery, the digital display will show three dashes
("---") for a period as long as several seconds while the tester analyzes the
battery.
Using the Alternator Performance Tester
Overview
This battery charger has a built-in alternator tester that displays an esti-
mate of the alternator's relative output compared to normal alternators.
The alternator % values displayed should be taken as a general reference,
not a precise diagnosis. The alternator tester functions the same as the
built-in battery voltage tester (see previous section for details) with a few
differences.
Testing Sequence: There are three basic steps required to operate this
unit as an alternator 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. Plug the charger AC power cord into the AC outlet, following the in-
structions given in Section 8.
3. Start the vehicle, and turn on the vehicle's headlights. Read the voltage
on the digital display or press the DISPLAY MODE button to set the
tester to ALTERNATOR % to read the voltage as a percent of charge.
Alternator Testing Note: The DISPLAY MODE cannot be set to ALTER-
NATOR % during charging.
General Charging Notes
Fan: The charger is designed to control its cooling fan for efficient opera-
tion. Consequentially, it is normal for the fan to start and stop when main-
taining a fully charged battery. The fan does not run in Tester Mode. Keep
the area near the charger clear of obstructions to allow the fan to operate
efficiently.
Restart: If the Charge Mode is changed after charging has started (by
pressing the BATTERY SIZE or BATTERY TYPE button), the charging
process will restart.
Voltage: The voltage displayed during charging is the charging voltage
and is usually higher than the battery's resting voltage.
