REASON/SOLUTION
The battery won't hold a charge. 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.
The charger automatically shuts the current off if it
detects the battery may be getting too hot. 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 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
60A Boost rate for 10 to 15 minutes, to
help assist in cranking.
The battery may be defective. Make sure
there are no loads on the battery. If there
are, remove them. If there are none, have
