DESCRIPTION
POSSIBLE CAUSE
The charger is in tester mode,
not charger mode.
You might have accidentally
activated a special diagnostic
mode.
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 the charger
can deliver within 24 hours. The
battery may also be faulty.
The battery may be fully charged
or recently charged, leaving the
battery voltage high enough to
appear to be fully charged.
The incorrect battery type may
have been selected.
REASON/SOLUTION
The battery could be bad. Have it checked or
replaced.
The battery could not be desulfated; have it
checked or replaced.
May be caused by trying to charge a large
battery or bank of batteries on too low of a
current setting. Try again with a higher current
setting or have the battery checked or replaced.
The battery is connected backwards. Unplug
the charger and reverse the connections to the
battery.
The battery won't hold a charge. May be
caused by a drain on the battery or the battery
could be bad. Make sure there are no loads
on the battery. If there are remove them. If
there are none, have the battery checked or
replaced.
The charger automatically shuts the current off
if it detects the battery may be getting too hot.
Have the battery checked or replaced.
Press the BATTERY SIZE
button to activate charging and
select a charge rate.
Make sure nothing is touching
the control panel, then unplug
the charger and plug it in again.
Reset the charger by briefly
unplugging it or briefly
disconnecting the negative
battery clamp. Select the
desired rate (SMALL or LARGE
BATTERY) and BATTERY
TYPE again, if necessary.
If the battery is in a vehicle,
turn the headlights on for a few
minutes, to reduce the battery
voltage; then try charging again.
Reset the charger, by briefly
unplugging it or briefly
disconnecting the negative
