Maintenance And Care; Troubleshooting And Error Codes - Schumacher SC1281 Owner's Manual

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.

Troubleshooting
PROBLEM
Battery clamps do not
spark when touched
together.
The charger will not
turn on when properly
connected.
The battery could be bad. Have it checked or
replaced.
The battery could not be desulfated; have it
checked or replaced.
May be caused by trying to charge a large battery or
bank of batteries on too low of a current setting. Try
again with a higher current setting or have the battery
checked or replaced.
The battery is connected backwards. Unplug the
charger and reverse the connections to the battery.
The battery won't hold a charge. May be caused by
a drain on the battery or the battery could be bad.
Make sure there are no loads on the battery. If there
are remove them. If there are none, have the battery
checked or replaced.
The charger automatically shuts the current off if
it detects the battery may be getting too hot. Have
the battery checked or replaced.
POSSIBLE CAUSE
The charger is equipped with
an auto-start feature. It will not
supply current to the battery
clamps until the START button
is pressed. The clamps will not
spark if touched together.
AC outlet is dead.
Poor electrical connection.
• 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.
REASON/SOLUTION
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.
