REASON/SOLUTION
SOLUTION
Check for open fuse or circuit
breaker supplying AC outlet.
Check power cord and extension
cord for loose fitting plug.
Have the battery checked.
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 Boost rate for 10 to 15
minutes, to help assist in cranking.
