REASON/SOLUTION
Plug the charger into an AC
outlet.
Check for open fuse or
circuit breaker supplying AC
outlet.
Check for poor connection
to battery and frame. Make
sure connection points are
clean. Rock clips back and
forth for a better connection.
Unplug the charger and
reverse the clips.
Have battery checked.
Continue charging battery for
two more hours. If problem
continues have the battery
checked.
Verify the voltage settings on
the charger are correct.
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 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.
