PROBLEM
POSSIBLE CAUSE
SOLUTION
Engine start does
not work.
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 less than 5 seconds.
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
50A Boost rate for 10 to 15 minutes, to
help assist in cranking.

none, have the battery checked or
replaced.
