12.2 INLINE FUSES
Inline fuses, located close to the ends of the red leads, protect the charger
from extremely high voltage surges, lightning strikes or other high current
surges. If a fuse blows, replace only with AGC-30 30A 32V 1 ¼” glass fuse.
12.3 LED DISPLAY
Red blinking (slow) –indicates check battery connection or blown fuse
Red blinking (fast) –indicates error, abort stage
Red solid – charger is charging, current at maximum
Yellow #1 solid –charger is charging, voltage >14.2 volts
Yellow #1 blinking – desulfation mode
Yellow #2 solid –charger is charging, constant voltage
Green solid – charger is in nal 3-hour charge. 95% charged
Green blinking – charge complete maintain stage
NOTE: When both output leads are connected to one battery, only
channel one will display the charge status of the battery.
12.4 AUTOMATIC CHARGE MODE
The automatic charger uses a three-step charging process. During the
BULK charge phase, the charger attempts to deliver 10/(20) amps of
current to the battery(ies) until the battery voltage levels off. At this point,
the charger enters the ABSORPTION charge phase. In this phase, the
charger will hold the battery voltage constant and let the battery determine
the charging current. When the charging current stabilizes, the charger will
continue to charge for three hours to bring the battery up to full charge.
The charger will then automatically enter the MAINTAIN MODE. During
this phase, the charger will hold the battery voltage constant at 13.2 volts
to guard against self-discharge of the battery. The charge current will
typically be a few tenths of an amp.
12.5 DESULFATION MODE
If the battery has been left discharged for an extended period of time, it
may have become ‘SULFATED’. If the battery voltage is less than 12.2
volts prior to being charged, and the voltage climbs rapidly when charging
begins, the battery may be SULFATED. Under this condition, the charger
enters DESULFATION MODE; this is indicated by the rst YELLOW LED
blinking. In DESULFATION MODE, the initial charging current is very
