12. MAINTENANCE AND CARE
A minimal amount of care can keep your
battery charger working properly for years.
• Clean the clamps each time you are
nished charging. Wipe off any battery
uid that may have come in contact with
the clamps to prevent corrosion.
• Occasionally cleaning the case of the
charger with a soft cloth will keep the
nish shiny and help prevent corrosion.
• Coil the input and output cords neatly
when storing the charger. This will help
prevent accidental damage to the cords
and charger.
• Store the charger unplugged from the AC
power outlet in an upright position.
• Store inside, in a cool, dry place. Do not
store the clamps on the handle, clipped
together, on or around metal, or clipped
to the cables.
13. TROUBLESHOOTING
PROBLEM POSSIBLE CAUSE 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 tting plug.
Have the battery checked.
The Boost-Charging
LED is ashing.
The charger has stopped in
Boost or Charge mode.
The battery is bad.
The charger cannot complete the boost
or charge. Have the battery checked and
replace, if necessary.
Disconnect charger from the AC outlet and
then remove the clamps. Do not continue
to try to charge the battery. Have the
battery checked and replace, if necessary.
The Boost-Charging
LED does not turn off.
The charger is still in Boost or
Charge mode.
This is normal. The Boost-Charging
LED will not turn off until the battery is
disconnected from the charger.
Charger does not
detect a low voltage
battery.
The charger was on for more
than 5 minutes before it was
connected to the battery.
The clamps are active for only the rst 5
minutes. Switch to the OFF position and
connect the charger to the battery. Set
the switch to the Boost/Charge/Maintain
position. Then push the rate selection
button to turn on the charger.
Engine start does
not work.
Drawing more than 200 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 200 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.
