Troubleshooting
PROBLEM
Battery clamps do not
spark when touched
together.
Three LEDs come on
for 2 seconds, then
turn off.
The charger will not
turn on when properly
connected.
Short or no start cycle
when cranking engine.
I cannot select a 6V or
12V setting.
I press the display
button, but do not
see the percentage of
charge.
POSSIBLE CAUSE
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.
The charger is plugged into an
AC outlet.
AC outlet is dead.
Poor electrical connection.
Drawing more than the Engine
Start Rate.
Failure to wait 3 minutes (180
seconds) between cranks.
Clamps are not making a
good connection.
AC cord and/or extension cord
is loose.
No power at receptacle.
The charger may be
overheated.
Battery may be severely
discharged.
The charger is equipped
with Auto Voltage Detection,
which automatically detects
the voltage and charges the
battery.
When first connected to a
battery, the display shows
voltage only.

REASON/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.
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.
Wait 3 minutes of rest time before
the next crank, to allow the battery
and charger to cool down.
Check for poor connection at
battery and frame.
Check power cord and extension
cord for loose fitting plug.
Check for open fuse or circuit
breaker supplying AC outlet.
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.
On a severely discharged battery,
use the 30A Boost rate for few
minutes, to help assist in cranking.
No problem; this is normal.
This is normal. The percentage
of charge is only displayed during
charging.
