Troubleshooting

PROBLEM
Battery clips do not spark
when touched together.
The charger is making an
audible clicking sound.
Charger makes a loud buzz
or hum.
CONNECTED (red) LED is
not on.
DESCRIPTION
POSSIBLE CAUSE
The charger is equipped
with an auto-start feature. It
will not supply current to the
battery clips until a battery
is properly connected.
Meaning, the clips will not
spark if touched together.
Circuit breaker is cycling.
Battery is defective.
Shorted battery cables or
clips.
Severely discharged battery,
but otherwise it is a good
battery.
Reverse connections at
battery.
Transformer laminations
vibrate (buzz).
Shorted Diode Assembly or
Output Rectifier Assembly
(hum).
Clips are not making a good
connection to the battery.
Connections are reversed.
Battery is defective (will not
accept a charge).
The charger automatically shuts the current
off if it detects the battery may be getting
too hot or the battery may have a shorted
cell. Have the battery checked or replaced.
No problem, this is a normal
condition.
The settings may be wrong.
Check the charger settings.
Have the battery checked.
Circuit breaker cycles when
current draw is too high.
Check for shorted cables
or clips 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.
No problem, this is a normal
condition.
Have charger checked by a
qualified technician.
Check for poor connection
to battery and frame. Make
sure connection points are
clean. Rock clips back and
forth for a better connection.
Unplug the charger and
reverse the clips.
Have battery checked.
