POSSIBLE CAUSE
Circuit breaker is cycling.
Battery is defective.
Shorted battery clamps.
Severely discharged battery,
but otherwise a good battery.
Reversed connections at
battery.
The battery is sulfated.
Vehicle drawing more than
the Engine Start rate.
Failure to wait 3 minutes (180
seconds) between cranks.
The charger may be
overheated.
Battery may be severely
discharged.

Under certain conditions, this unit
has a high capacity and the circuit
breaker protects the unit under
these conditions. If the circuit
breaker is cycling often, stop the
operation by pressing the START/
STOP button and wait until the unit
has cooled, to return to operation.
Have the battery checked.
Circuit breaker cycles when current
draw is too high. Check for shorted
cables and replace if necessary.
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.
Correct the lead connections.
A sulfated battery may eventually
take a normal charge if left
connected. The charger will continue
to charge with a low current for up to
10 hours to recover the battery. If the
battery will not take a charge after 10
hours, have it checked.
Crank time varies with the amount
of current drawn. If cranking draws
more than the Engine Start rate,
crank time may be reduced.
When the
blinks, 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,
use the
minutes, to help assist in cranking.
