|
PROBLEM
|
POSSIBLE CAUSE
|
SOLUTION
|
|
No reading on the ammeter.
|
Charger is not plugged in.
|
Plug the charger into an AC
outlet.
|
|
No power
at the receptacle.
|
Check for open fuse or circuit
breaker supplying AC outlet.
|
|
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.
|
|
2 amp
charge rate is being used.
|
Ammeter may show no activity at
the 2A charge rate.
|
|
Ammeter reading stays high.
|
Battery is severely discharged.
|
Continue charging battery for
two more hours. If problem continues have the battery checked.
|
|
Wrong
battery voltage.
|
Verify the voltage settings on
the charger are correct.
|
|
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.
|
|
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.
|
|
Ammeter reads less than selected charge rate when charging a
discharged battery
|
Extension cord is too long or
wire gauge is too small.
|
Use a shorter or heavier gauge
extension cord.
|
|
Weak
cell or sulfated plate in battery.
|
A sulfated battery will
eventually take a normal charge if left connected. If the battery will not
take a charge, have it checked.
|
|
Battery
is only partially discharged.
|
Continue to charge the battery.
|
|
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.
|
|
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 to allow the battery and charger to cool down.
|
|
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 close. 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 highest manual rate to help
assist in cranking.
