REASON/SOLUTION
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 neces-
sary.
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 connec-
tions.
No problem, this is a normal
condition.
Crank time varies with the
amount of current drawn. If
cranking draws more than
55 amps, 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 amp rate
to help assist in cranking.
