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

Drawing more than 200 amps.
Failure to wait 3 minutes (180
seconds) between cranks.
The charger may be overheated.

discharged.
Crank time varies with the amount
of current drawn. If cranking
draws more than 200 amps, 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
40A Boost rate for 10
to 15 minutes, to help assist in
cranking.
