REASON/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 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 35A Boost rate for 10 to 15
minutes, to help assist in cranking.
The charger cannot complete
the boost or charge. Have the
battery checked and replace, if
necessary.
Disconnect charger from the
AC outlet and then remove the
clamps. Do not continue to try
to charge the battery. Have the
battery checked and replace, if
necessary.
