PROBLEM POSSIBLE CAUSE REASON/SOLUTION
CHECK (red) LED is on. Clips are not making a good
connection to the battery.
Connections are reversed.
Battery is severely
discharged or defective.
Check for a poor connection
to the battery. Make sure the
connection points are clean.
Unplug the charger and
reverse the clips.
Have the battery checked.
The battery is connected and
the charger is on but is not
charging.
The charger is in Test Mode
not Charge Mode.
Press the CHARGE,
OUTPUT or BANK button
until the ON or CHARGE
LED lights.
Indicator lights are lit in an
erratic manner not explained
in the manual.
A button may have been
pressed as the charger was
plugged into the 120V AC
outlet.
Make sure nothing is
touching the control panel,
then unplug the charger, wait
a moment, and plug it back in.
CHECK (red) LED always
flashes before the battery is
completely charged.
This will happen if the battery
did not reach a full charge
within 24 hours. That may be
due to a very large battery or
a bank of batteries requiring
more power than the charger
can deliver in 24 hours.
Battery may be defective.
Reset the charger by
unplugging the charger from
the 120V AC outlet, waiting
a moment, then plugging
it back in and starting the
charge cycle again.
Have the battery checked.
The CHARGED (green) LED
turns on a few minutes after
connecting the charger to the
battery.
The battery may be fully
charged or recently charged
leaving the battery voltage
high enough to appear to be
fully charged.
If the battery is in a vehicle,
turn the headlights on for
a few minutes to reduce
the battery voltage and try
charging it again.
The measured current is
much lower than expected.
The charger has reached
the maximum voltage and is
reducing the current.
The charger detected an
over-temperature condition
and has reduced the current
to allow the charger to cool.
No problem; this is a normal
condition.
See the “Over-temperature
Protection” section of the
manual.
The CHECK (red) LED is
blinking. NOTE: The digital
display (if present) blinks
when the CHECK LED blinks.
Indicates the charger is in
Abort Mode.
See “Aborted Charge”
in the OPERATING
INSTRUCTIONS” Section.
