REASON/SOLUTION
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.
No problem, this is a normal
condition.
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.
See "Aborted Charge" in the
OPERATING INSTRUCTIONS
Section.
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.
Wait 3 minutes of rest time
before the next crank.
Check for poor connection at
battery and frame.
Check power cord and
extension cord for loose fitting
plug.
Check for open fuse or circuit
breaker supplying AC outlet.
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.
On a severely discharged
battery, charge for 10 to 15
minutes in the 10◄►25 amp
charge rate to help assist in
cranking.
