TROUBLESHOOTING AND ERROR CODES

DESCRIPTION
POSSIBLE CAUSE
AC outlet is dead.
Poor electrical connection.
Battery is defective.
The charger is plugged into an
AC outlet.
Drawing more than 200 amps.
Failure to wait 3 minutes (180
seconds) between cranks.
The charger may be
overheated.
Battery may be severely
discharged.
REASON/SOLUTION
The battery could be bad. Have it checked or replaced.
The battery could not be desulfated; have it checked or
replaced.
May be caused by trying to charge a large battery or bank of
batteries on too low of a current setting. Try again with a higher
current setting or have the battery checked or replaced.
The battery is connected backwards. Unplug the charger and
reverse the connections to the battery.
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.
No problem; this is normal.
Crank time varies with the
amount of current drawn. If
cranking draws more than 200
amps, 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 Boost rate for 10 to 15
minutes, to help assist in cranking.
