Maintenance And Care; Troubleshooting - Schumacher Electric SC11 Manual Del Usuario

ENGINE STARTING NOTES
During the starting sequence listed above,
the charger is set to one of three states:
• Wait for cranking – The charger waits
until the engine is actually being cranked
before delivering the amps for engine
start and will reset if the engine is not
cranked within 15 minutes. If the charger
resets, it sets itself to the default start up
settings.

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
finished charging. Wipe off any battery
fluid 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
finish shiny and help prevent corrosion.

13. TROUBLESHOOTING

PROBLEM
Battery clamps do not
spark when touched
together.
The charger will not
turn on when properly
connected.
The battery is properly
connected, but the
% CHARGE/BOOST
LEDs never lit.
The BAD BATTERY
LED is lit and the
% CHARGE/BOOST
LEDs are flashing.
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.

The battery voltage is still below
10V after 2 hours of charging.
(or)
In maintain mode, the output
current is more than 1.5A for 12

Desulfation was unsuccessful.
• Cranking – When cranking is detected,
the charger will automatically deliver up
to its maximum output as required by the
starting system for up to 3 seconds or until
the engine cranking stops.
• Cool Down – After cranking, the charger
enters a mandatory 3 minute (180 second)
cool down state. This is indicated by the
blinking ENGINE START LED. After three
minutes, the % CHARGE/BOOST LEDs
will light in sequence and the ENGINE
START LED will be lit.
• 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 clipped together, on or
around metal, or clipped to the cables.
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.
Press the START/STOP button to
start charging.
The battery may be defective.
Make sure there are no loads on
the battery. If there are, remove
them. If there are none, have the
battery checked or replaced. To
reset the charger, unplug from the
AC outlet, wait a few moments and
plug it back in.
The battery may be defective. Have
battery checked or replaced.
