Schumacher PS-2100MA Troubleshooting Guide
PROBLEM POSSIBLE CAUSE SOLUTION
No meter reading. Connections are reversed. With charger unplugged, reverse clamps and reconnect. (Rock clamps back and forth to ensure clamps are connected.)
Poor electrical connection. Clean clamps and battery posts and reconnect. (Rock clamps back and forth to ensure clamps are connected.)
AC outlet is dead. Plug in a lamp or other appliance to check for voltage.
Battery is defective (will not accept charge). Have battery checked.
Charger will not turn on (when properly connected to power) in automatic mode only. Battery recently charged as result of driving and is fully charged. Battery does not need charging. (Turning on headlights will lower battery voltage in a few seconds and charger should then turn on.)
Charger will not turn OFF. Battery has problem and will not take full charge, or it is a manual charger. Have battery checked.
Meter needle fluctuates back and forth from the middle to the left. Battery has reached Full Charge and and is not able to maintain above 13V. Have battery checked.
Meter needle pulses (fluctuates) every few seconds AFTER THREE HOURS without slowing down. Two or more batteries connected in parallel. Do not parallel charge.
Battery of 200 ampere hours or larger. Requires more time to charge: continue charging.
Battery is connected to a device that draws a small current (such as an interior light). Use larger device.
Meter needle moves to extreme right, remains a short time, then returns to zero, accompanied by a clicking sound. Battery is severely discharged (but otherwise good). Allow charging to continue until battery has recovered sufficiently to take a charge. (Circuit breaker will continue to cycle and needle will swing side to side until battery has recovered.)
Battery is defective (will not accept charge). Have battery checked.
Charger is cycling after circuit breaker overload. Wait until charger automatically resets itself.

When a charging problem arises, make certain that the battery is capable of accepting a normal charge. Double check all connections, AC outlet for a full 120-volts, charger clips for correct polarity and the quality of the connections from the cables to the clips and from the clips to the battery system. The clips must be clean.

When a battery is very cold, partially charged or sulfated, it will not draw the full rated amperes from the charger. It is both dangerous and damaging to a battery to force higher amperage into it than it can effectively use in recharging.
