Maintenance And Care; Troubleshooting - Schumacher Electric SE-125A Owner's Manual

13. 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.

PROBLEM
The charger will not
turn on when properly
connected.
The battery is
connected and the
charger is on, but is
not charging.
The charger is making
an audible clicking
sound.

Shorted diode assembly or output
rectifier assembly (hum).
The battery may be sulfated or
unable to hold the charge.
• 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.
Check for open fuse or circuit
breaker supplying AC outlet.
Check power cord and extension
cord for loose fitting plug.

points are clean. Rock clamps back
and forth for a better connection.

the charger settings.
Have the battery checked.
Circuit breaker cycles when current
draw is too high. Check for shorted
cables or clamps and replace, if
necessary.
The battery may not want to accept
a charge due to a run-down state.
Allow charging to continue until
battery has a chance to recover
sufficiently to take a charge. If more
than 20 minutes, stop charging and
have the battery checked.
Shut the charger off and correct
the lead connections.
No problem; this is a normal
condition.
Have charger checked by a
qualified technician.
Continue charging. If the battery
does not take a charge after 8
hours, have the battery checked.
