Battery clamps do not
spark when touched
together.
All three LEDs come
on for 2 seconds, then
turn off.
The charger will not
turn on when properly
connected.
I cannot select a 6V or
12V setting.

will not supply current to the
battery clamps until a battery
is properly connected. The
clamps will not spark if
touched together.
The charger is plugged into
an AC outlet.
AC outlet is dead.
Poor electrical connection.
Connections are reversed.
Battery is defective.
The charger is equipped
with Auto Voltage Detection,
which automatically detects
the voltage and charges the
battery.

SOLUTION
No problem; this is a normal
condition.
No problem; this is normal.
Check for open fuse or circuit
breaker supplying AC outlet.
Check power cord and extension
cord for loose fitting plug.
Unplug the charger and reverse
the clamps. (The charger will
not detect reversed connections
when the battery voltage is less
than 2V.)
Have battery checked.
