Troubleshooting
PROBLEM
POSSIBLE CAUSE
REASON/SOLUTION
Charger will not turn
on when properly
connected.
AC outlet is dead.
Poor electrical connection.
Battery is defective.
Check for open fuse or circuit
breaker supplying AC outlet.
Check power cord and extension
cord for loose fitting plug.
Have the battery checked.
Three LEDs come on for
2 seconds, then turn off.
The charger is plugged into an
AC outlet.
No problem; this is normal.
Engine start does
not work.
Drawing more than 250 amps.
Failure to wait 3 minutes (180
seconds) between cranks.
The charger may be
overheated.
Battery may be severely
discharged.
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.
The Boost LED shuts
off.
The Boost mode is completed. This is normal. The charger will
automatically switch to charging
mode to fully charge the battery.
Or you may press the
Rate
Selection button and select
either the 6A<>2A CHARGE/
MAINTAIN rate or
ENGINE
START.
