Battery is defective.
Check for open fuse or circuit breaker
supplying AC outlet.
Check power cord and extension cord

Drawing more than the
Engine Start rate.
Failure to wait 3 minutes (180
seconds) between cranks.

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

Wait and try again.
On a severely discharged battery, use the
60A Boost rate for 10 to 15 minutes, to
help assist in cranking.
