Troubleshooting
PROBLEM
Battery clamps do not
spark when touched
together.
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 plug in the charger,
but do not see the
percentage of charge.
The battery is correctly
connected, but the
CHARGING LED did not
light immediately.
The battery is properly
connected, but the
CHARGING LED
never lit.
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.
AC outlet is dead.
Poor electrical connection.
Battery is defective.
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.
If the START/STOP button is
not pressed, charging should
begin in ten minutes.
The battery voltage is low.
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.
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 setting 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.
No problem; this is normal.
Press the START/STOP button to
start charging.
