PROBLEM
POSSIBLE CAUSE
SOLUTION
Short or no start cycle
when cranking engine.
No power at receptacle.
AC cord and/or extension
cord is loose.
The clamps are not making a
good connection.
Failure to wait 3 minutes
between cranks.
The battery may be severely
discharged.
The battery is drawing more
than the engine start rate.
The charger may be
overheated.
Check for open fuse or circuit
breaker supplying AC outlet.
Check power cord and extension
cord for loose fitting plug.
Check for poor connection at
battery and frame.
Wait 3 minutes of rest time
before the next crank.
On a severely discharged
battery, use the 40A
Boost
rate for 10 to 15 minutes, to
assist in cranking.
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.
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.
