Troubleshooting
PROBLEM
Charger will not turn
on when properly
connected.
Engine start does
not work.
DESCRIPTION
POSSIBLE CAUSE
AC outlet is dead.
Poor electrical connection.
Battery is defective.
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 charger will go into desulfation mode. If the
desulfation is not successful after 10 hours, the charger
will go into abort mode.
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.
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
to 15 minutes, to help assist in
cranking.
