PROBLEM
POSSIBLE CAUSE
REASON/SOLUTION
Ammeter reading
stays high.
Battery is severely discharged.
Wrong battery voltage.
Continue charging battery for two
more hours. If problem continues
have the battery checked.
Verify the voltage settings on the
charger are correct.
Ammeter reads less
than selected charge
rate when charging
a discharged battery.
Extension cord is too long or
wire gauge is too small.
Weak cell or sulfated plate in
battery.
Battery is only partially
discharged.
Use a shorter or heavier gauge
extension cord.
A sulfated battery will eventually
take a normal charge if left
connected. If the battery will not
take a charge, have it checked.
Continue to charge the battery.
The charger is
making an audible
clicking sound.
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.
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.
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.
