PROBLEM
I cannot select a 6V or
12V setting.
Battery clamps do not
spark when touched
together.
The LED does not
light when charger is
properly connected.
Short or no start cycle
when cranking engine.
The battery is properly
connected, but the
CHARGING/BOOST/
ENGINE START LED
never lit.
POSSIBLE CAUSE
The charger is equipped with
Auto Voltage Detection, which
automatically detects the
voltage and charges the battery.
The charger is equipped
with an auto-start feature.
It will not supply current to
the battery clamps until a
battery is properly connected.
The clamps will not spark if
touched together.
AC outlet is dead.
Poor electrical connection.
Battery is defective.
No power at receptacle.
AC cord and/or extension cord
is loose.
The clamps are not making a
good connection.
Failure to wait 3 minutes (180
seconds) between cranks.
The battery may be severely
discharged.
The battery is drawing more
than the Engine Start Rate.
The charger may be
overheated.
The battery voltage is low.
No problem; this is normal.
No problem; this is a normal
condition.
Check for open fuse or circuit
breaker supplying AC outlet.
Check power cord and extension
cord for loose fitting plug.
Have battery checked.
Check for open fuse or circuit
breaker supplying AC outlet.
Check power cord and extension
cord for loose fitting plug.
Check for poor connection at
battery and frame.
Wait 3 minutes of rest time before
the next crank, to allow the battery
and charger to cool down.
On a severely discharged battery,
use the 10A BOOST setting for few
minutes, to help assist in cranking.
Crank time varies with the amount
of current drawn. If cranking draws
more than the Engine Start Rate,
crank time may be less than 3
seconds.
The thermal protector may have
tripped and needs a little longer to
close. Make sure the charger vents
are not blocked. Wait and try again.
Press the START/STOP button to
start charging.
