PROBLEM
POSSIBLE CAUSE
REASON/SOLUTION
The charger is making
an audible clicking
sound.
Circuit breaker is cycling.
Battery is defective.
Shorted battery cables or clamps.
Severely discharged battery, but
otherwise it is a good battery.
Reverse connections at battery.
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
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.
Short or no start cycle
when cranking engine.
Drawing more than the charger’s
rated amps.
Failure to wait 3 minutes (180
seconds) between cranks.
Clamps are not making a good
connection.
AC cord and/or extension cord is
loose.
No power at receptacle.
The charger may be overheated.
Battery may be severely discharged.
Crank time varies with the amount of
current drawn. If cranking draws more
than the charger’s rated amps, crank
time may be less than 3 seconds.
Wait 3 minutes before the next crank.
Check for poor connection at battery
and frame.
Check power cord and extension cord
for loose fitting plug.
Check for open fuse or circuit breaker
supplying AC outlet.
The thermal protector may have tripped
and needs a little longer to reset. Make
sure the charger vents are not blocked.
Wait and try again.
On a severely discharged battery, charge
for 10 to 15 minutes in the manual charge
rate to help assist in cranking.
Charger will not turn
on when properly
connected.
AC outlet is dead.
Poor electrical connection.
Check for open fuse or circuit breaker
supplying AC outlet.
Check power cord and extension cord
for loose fitting plug.
The battery is
connected and the
charger is on, but is
not charging.
Clamps are not making a good
connection.
Check for poor connection at battery
and frame. Make sure connecting
points are clean. Rock clamps back and
forth for a better connection.
