Crank time varies with the
amount of current drawn. If
cranking draws more than the
engine start rate, crank time
may be less than 3 seconds.
Wait 3 minutes of rest time
before the next crank.
Check for poor connection at
battery and frame.
Check power cord and
extension cord for loose
fitting plug.
Check for open fuse or circuit
breaker supplying AC outlet.
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, charge for 10 to 15
minutes at the lowest rate, to
help assist in cranking.
