PROBLEM
POSSIBLE CAUSE
SOLUTION
Clicking noise from charger. Circuit breaker is cycling.
Battery is defective.
Shorted battery clamps.
Severely discharged battery, but
otherwise a good battery.
Reversed connections at battery.
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.
Display shows “
SUL
”
The battery is sulfated.
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.
Engine start does not work. 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.
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 Engine Start LED 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 Boost rate for 10 to 15 minutes, to
help assist in cranking.
