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 clamps 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.
Have charger checked by a
qualified technician.
Crank time varies with the
amount of current drawn. If
cranking draws more than 150
amps, crank time may be less
than 3 seconds.
Wait 3 minutes of rest time
before the next crank.
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, to
help assist in cranking.
