Sears 200.71225 - Manual (Page 12)

USING THE BUILT-IN ALTERNATOR TESTER
This battery charger has a built-in alter­
nator tester that displays either an accu­
rate alternator voltage or an estimate of
the alternator’s relative output compared
to normal alternators. The Alternator %
values displayed should be taken as
general reference, not precise diagnosis.
The alternator tester functions the same
as the battery tester (see previous sec­
tion of this manual for details) with a few
differences.
TESTING SEQUENCE
There are three basic steps required to use
the 71225 as an alternator tester.
1. Connect the charger battery clamps
to the battery or charging system. Be
sure to follow all of the precautions
listed under “OPERATING INSTRUC­
TIONS”.
2. Connect the charger power cord to a
120V AC 2-prong wall outlet. Again,
be sure to follow all of the precautions
listed under “OPERATING INSTRUC­
TIONS”.
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 % and read
the alternator percent.
TESTER STATUS LEDs
When the 71225 is operating as an alterna­
tor tester, the status LEDs light under the
following conditions.
• The CHARGED (green) LED will light
if the output of the charging system is
at the normally desired level.
• The CHARGING (yellow) LED does
not light in the alternator test mode.
• The CHECK (red) LED lights if the
voltage Is much higher or lower than
normally desired.
• When the tester display mode is set
to VOLTAGE, the CHARGED and
CHARGING LEDs won't light (it could
be testing a battery or an alternator).
ALTERNATOR TESTING NOTES
• The alternator percent display can
range from 0 to 199.
• The DISPLAY MODE cannot be set to
ALTERNATOR % during charging.
