SOLUTION
The battery is connected
and the charger is on,
but isn't charging.

mode, not charger mode.
Press the CHARGE
START button to activate
charging and select a
charge rate.
Indicator lights are lit in
an erratic manner not
explained in the “Using
Your Battery Charger”
section.
You might have acciden-
tally activated a special
diagnostic mode.
The charger may be
defective.
Make sure nothing is
touching the control
panel, then unplug the
charger and plug it in
again.
Return to place of pur-
chase for replacement.
The DIGITAL DISPLAY
always flashes before
the battery is completely
charged.
The incorrect BATTERY
TYPE may have been
selected.
This will happen if the
battery did not reach full
charge within 24 hours.
May be due to a very
large battery or a bank of
batteries requiring more
power than a 10A25A
amp charger can deliver
within 24 hours. The bat-
tery may also be faulty.
Reset the charger by
briefly unplugging it or
briefly disconnecting the
negative battery clip.
Select the desired rate
(SMALL or REGULAR
BATTERY) and BAT-
TERY TYPE again, if
necessary.
Engine crank time is less
than specified.
Starter motor may be
drawing more than 80
amps.
Charge the battery at the
REGULAR BATTERY
rate for 10 to 15 minutes
then crank the engine.
The green CHARGED
LED lights a few minutes
after connecting to the
battery.
The battery may be
fully charged or recently
charged, leaving the bat-
tery voltage high enough
to appear to be fully
charged.
The incorrect BATTERY
TYPE may have been
selected.
If the battery is in a ve-
hicle, turn the headlights
on for a few minutes
to reduce the battery
voltage and try charging
again.
Reset the charger by
briefly unplugging it or
briefly disconnecting the
negative battery clip.
Select the desired rate
(SMALL or REGULAR
BATTERY) and BAT-
TERY TYPE again, if
necessary.
