Schumacher PS-2100MA (New Style)Troubleshooting Guide
Problem	Possible Cause	Reason / Solution
Battery clamps do not spark when touched together	The charger is equipped with anauto-start feature. It will not supply current to the battery clampsuntil a battery is properly connected. The clamps will not spark iftouched together.	No problem; this is a normalcondition
All three LEDs come on for 2 seconds, then turn off.	The charger is plugged into an ACoutlet	No problem; this is normal
Thecharger will not turn on when properly connected.	AC outlet is dead	Check for open fuse or circuitbreaker supplying AC outlet

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.
