|
FAILURE
CODE
|
DESCRIPTION
|
CAUSE
|
|
F01
|
The battery voltage is still
under 10V (for a 12V battery) or 5V (for a 6V battery) after 2 hours of
charging.
|
Could be caused by trying to
charge a 6 volt battery on the 12 volt charger, or the battery could be bad;
have it checked or replaced.
|
|
F02
|
The charger cannot desulfate the
battery.
|
The battery could not be
desulfated; have it checked or replaced.
|
|
F03
|
The battery was unable to reach
the “full charged” voltage.
|
Could be caused by trying to
charge a large battery or bank of batteries on too low of a current setting,
or the battery may have a shorted cell. Try again with a higher current
setting, or have the battery checked or replaced.
|
|
F05
|
The charger was unable to keep
the battery fully charged in maintain mode.
|
The battery won’t hold a charge.
Could 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.
|
|
F06
|
The charger detected that the
battery may be getting too hot (thermal runaway).
|
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.
|
|
If you get a failure code you have to check the connections and
settings and / or replace the battery.

SE-1555A Troubleshooting Guide
|
|
PROBLEM
|
POSSIBLE CAUSE
|
SOLUTION
|
|
Battery clips do
not spark when touched together.
|
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.
|
No problem, this is a normal
condition.
|
|
The charger is making an audible clicking sound.
|
Circuit breaker is cycling.
|
The settings may be wrong. Check
the charger settings.
|
|
Battery
is defective.
|
Have the battery checked.
|
|
Shorted
battery cables or clips.
|
Circuit breaker cycles when
current draw is too high. Check for shorted cables or clips and replace if
necessary.
|
|
Severely
discharged battery, but otherwise it is a good battery.
|
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.
|
|
Reverse
connections at battery.
|
Shut the charger off and correct
the lead connections.
|
|
Charger makes a loud buzz or hum.
|
Transformer laminations vibrate
(buzz).
|
No problem, this is a normal
condition.
|
|
Shorted
Diode Assembly or Output Rectifier Assembly (hum).
|
Have charger checked by a
qualified technician.
|
|
CONNECTED (red) LED is not on.
|
Clips are not making a good
connection to the battery.
|
Check for poor connection to
battery and frame. Make sure connection points are clean. Rock clips back and
forth for a better connection.
|
|
Connections
are reversed.
|
Unplug the charger and reverse
the clips.
|
|
Battery
is defective (will not accept a charge).
|
Have battery checked.
|
|
Short or no start cycle when cranking engine.
|
Drawing more than the Engine
Start rate.
|
Crank time varies with the
amount of current drawn. If cranking draws more than the Engine Start rate,
crank time may be less than 3 seconds.
|
|
Failure
to wait 4 minutes (240 seconds) between cranks.
|
Wait 4 minutes of rest time
before the next crank.
|
|
Clips
are not making a good connection.
|
Check for poor connection at
battery and frame.
|
|
AC cord
and/or extension cord is loose.
|
Check power cord and extension
cord for loose fitting plug.
|
|
No power
at receptacle.
|
Check for open fuse or circuit
breaker supplying AC outlet.
|
|
The
charger may be overheated.
|
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.
|
|
Battery
may be severely discharged.
|
On a severely discharged
battery, charge for 10 to 15 minutes in the 55 amp charge rate to help assist
in cranking.
|
|
Charger will not turn on when properly connected.
|
AC outlet is dead.
|
Check for open fuse or circuit
breaker supplying AC outlet.
|
|
Poor
electrical connection.
|
Check power cord and extension
cord for loose fitting plug.
|
|
Function
switch is in the OFF position.
|
Turn Function switch ON.
|
|
The
battery is connected and the charger is on, but is not charging.
|
Clips are not making a good
connection.
|
Check for poor connection at
battery and frame. Make sure connecting points are clean. Rock clips back and
forth for a better connection.
|
|
The
measured current is much lower than what was selected.
|
The charger reached the maximum
voltage and is reducing the current.
|
No problem, this is a normal
condition.
