TESTER AND CHARGER:14.2 When rst turned on, the 71225 operates only
as a tester, not as a charger. To continue to use it as only a tester, avoid
pressing the CHARGE RATE button. Selecting a charge rate activates the
battery charger and deactivates the tester. Pressing the CHARGE RATE but-
ton when the 80A Start LED is lit (except during the 180 second cool down)
will shut off the charger and activate the tester.
POWER-UP IDLE TIME LIMIT: 14.3 If no button is pressed within 15 minutes
after the battery is rst powered up, the charger will automatically switch
from tester to charger, if a battery is connected. In that case, the battery
will be set for the 2A charge rate and 12V REGULAR battery type.
TESTER WITHOUT TIME LIMIT:14.4 If either the DISPLAY MODE or BAT-
TERY TYPE button is pressed within the rst ten minutes after the battery
is powered up, the unit will remain a tester (not a charger) indenitely,
unless a charge rate is selected.
TESTING AFTER CHARGING:14.5 After the unit has been changed from
tester to charger (by selecting a charge rate), it remains a charger. To
change the battery back to a tester, press the CHARGE RATE switch until
all charge rate LEDs are off.
TESTER STATUS LEDs:14.6 When the 71225 is operating as a battery tester,
the status LEDs light under the following conditions:
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 CHECK (red) LED lights unless a properly connected battery is de-•
tected.
When the tester display mode is set to • VOLTAGE, the CHARGED and
CHARGING LEDs won’t light.
INITIAL PERCENT CALCULATION: 14.7 When a battery % is calculated for
the rst 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 BUILT-IN ALTERNATOR TO TEST ALTERNATOR 15.
OUTPUT
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 general reference,
not precise diagnosis. The alternator tester functions the same as the
built-in volt meter (see previous section of this manual for details) with a
few differences.
