PROBLEM POSSIBLE CAUSE SOLUTION
CONNECTED (red) light is
not on.
(Models: SC-600A,
SSC-1500A and SC-1200A)
CHECK (red) light is not on.
(Models: SC-1000A
and SSC-1000A)
The battery is not connected
correctly.
Connection to battery is
reversed.
The battery voltage is less
than one volt.
Check for poor connection to
battery and frame. Make sure
connection points are clean.
Rock clips back and forth for
a better connection.
Correct connection.
Replace the battery or try
using a manual charger to
bring above one volt.
Indicator lights are lit in
an erratic manner, not
explained in the Operating
Instructions.
A button may have been
pressed while the charger was
being plugged in.
Make sure nothing is touching
the control panel, then unplug
the unit and plug it in again.
CONNECTED (red) light is
blinking.
(Models: SC-600A and
SC-1000A)
Charger in abort mode.
Battery may also be faulty.
This will happen if the battery
did not reach full charge within
48 hours. May be due to a
very large battery or a bank
of batteries requiring more
power than the charger can
deliver in 48 hours.
Reset the charger by
unplugging it. Select the
desired CHARGE RATE
and battery type again, if
necessary.
The CHARGED (green)
light turns on a few minutes
or less after connecting the
battery.
The battery may be fully
charged or recently charged,
leaving the battery voltage
high enough to appear to be
fully charged.
The battery may be faulty
(sulfated).
If the battery is in a vehicle,
turn the headlights on for
a few minutes to reduce
the battery voltage and try
charging again. Also try
a lower CHARGE RATE
selection.
A sulfated battery will
eventually accept a charge.
Continue charging for a few
hours. The CHARGING
(yellow) LED will blink. If not,
have the battery checked or
call customer service.
The measured current is
much lower than what was
selected.
The charger reached the
maximum voltage and is
reducing the current.
No problem; this is a normal
condition.
