Troubleshooting
PROBLEM
POSSIBLE CAUSE
SOLUTION
The battery is connected
and the charger is on, but
isn’t charging.
The charger is in tester mode,
not charger mode.
Press the BATTERY SIZE
button to activate charging and
select a charge rate.
Indicator lights are lit in
an erratic manner, not
explained in this manual.
You might have accidentally
activated a special diagnostic
mode.
Make sure nothing is touching
the control panel, then unplug
the charger and plug it in again.
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 the charger
can deliver within 24 hours. The
battery may also be faulty.
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.
The green CHARGED
LED lights a few minutes
after connecting to the
battery.
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.
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
battery clamp. Select the
desired rate (SMALL or LARGE

again, if necessary.
The charger is making an
audible clicking sound.
Circuit breaker is cycling.
The battery is defective.
Shorted battery cables or
clamps.
Severely discharged, but
otherwise good battery.
Reversed connections to the
battery.

Check the charger settings.
Have the battery checked.
Circuit breaker cycles when
current draw is too high. Check
for shorted cables or clamps
and replace, if necessary.
The battery may not want to
accept a charge, due to a
run-down state. Allow charging
to continue until battery has a
chance to recover sufficiently
to take a charge. If more than
20 minutes, stop charging and
have the battery checked.
Shut the charger off and correct
the lead connections.
Charger makes a loud
buzz or hum.
Transformer laminations vibrate
(buzz).
Shorted Diode Assembly or
Output Rectifier Assembly (hum).
No problem, this is a normal
condition.
Have charger checked by a
qualified technician.
