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.

Wait and try again.
On a severely discharged
battery, charge for 10 to 15
minutes in the 10 amp manual
rate to help assist in cranking.

The charger reached the
maximum voltage and is
reducing the current.
