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

REASON/SOLUTION
The charger automatically shuts the current off if it
detects the battery may be getting too hot. Have the
battery checked or replaced.
Make sure the charger does not have the side ventilation
holes blocked. Move the charger out of the sun and into
the shade.
May be caused by a drain on the battery or the battery
could be bad. Make sure there are no loads on the
battery. If there are, remove them. If there are none,
have the battery checked or replaced.
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
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.
