Troubleshooting

PROBLEM
Charger will not turn
on when properly
connected.
Three LEDs come on for
2 seconds, then turn off.
Engine start does
not work.
The Boost LED shuts
off.
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.
POSSIBLE CAUSE
AC outlet is dead.
Poor electrical connection.
Battery is defective.
The charger is plugged into an
AC outlet.
Drawing more than 250 amps.
Failure to wait 3 minutes (180
seconds) between cranks.
The charger may be
overheated.
Battery may be severely
discharged.
The Boost mode is completed.
REASON/SOLUTION
REASON/SOLUTION
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 250
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 40A Boost rate for 10 to 15
minutes, to help assist in cranking.
This is normal. The charger will
automatically switch to charging
mode to fully charge the battery.
Or you may press the
Selection button and select
either the 6A<>2A CHARGE/
MAINTAIN rate or
START.
