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.
Check for an open fuse or circuit
breaker supplying the AC outlet.
Check power cord and extension
cord for loose fitting plug.
Check for poor connection at
battery and frame.
Wait 3 minutes of rest time
before the next crank.
On a severely discharged
battery, charge for 10 to
15 minutes at the LARGE
BATTERY rate, to help assist
in cranking.
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.
The thermal protector may have
tripped and needs a little longer
to close. Make sure the charger
vents are not blocked. Wait and
try again.
