POSSIBLE CAUSE
Drawing more than the
engine start rate.
Failure to wait 3 minutes (180
seconds) between cranks.
Clamps are not making a
good connection.
The charger may be
overheated.
Battery may be severely
discharged.
The charger is equipped
with Auto Voltage Detection,
which automatically detects
the voltage and charges the
battery.

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.
The thermal protector may
have tripped and needs a little
longer to close. 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 FAST
charge rate to help assist in
cranking.
No problem; this is normal.
