PROBLEM
The charger is mak-
ing an audible clicking
sound.
Charger makes a loud
buzz or hum.

NOTE:
If the above solutions do not eliminate the problem, or for information about troubleshooting or replacement parts,
call toll-free: 1-800-528-6817.
POSSIBLE CAUSE
• 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).
• AC outlet is dead.
• Poor electrical connection
Clips are not making a good
connection.
The charger reached the maximum
voltage and is reducing the current.
SOLUTION
• 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 open fuse or circuit
breaker supplying AC outlet.
• Check power cord and extension
cord for loose fitting plug.
Check for poor connection at battery
and frame. Make sure connecting points
are clean. Rock clips back and forth for
a better connection.
No problem; this is a normal condition.
