PROBLEM POSSIBLE CAUSE SOLUTION
No reading on the ammeter. Charger is not plugged in. Plug the charger into an AC outlet.
No power at the receptacle. Check for open fuse or circuit breaker supplying AC outlet.
Clips are not making a good connection to the battery. Check for poor connection to battery and frame. Make sure connection points are clean. Rock clips back and forth for a better connection.
Connections are reversed. Unplug the charger and reverse the clips.
Battery is defective (will not accept a charge). Have battery checked.
2 amp charge rate is being used. Ammeter may show no activity at the 2A charge rate.
Ammeter reading stays high. Battery is severely discharged. Continue charging battery for two more hours. If problem continues have the battery checked.
Wrong battery voltage. Verify the voltage settings on the charger are correct.
Charger will not turn on when properly connected. AC outlet is dead. Check for open fuse or circuit breaker supplying AC outlet.
Poor electrical connection. Check power cord and extension cord for loose fitting plug.
The battery is connected and the charger is on, but is not charging. Clips are not making a good connection. Check for poor connection at battery and frame. Make sure connecting points are clean. Rock clips back and forth for a better connection.
The measured current is much lower than what was selected. The charger reached the maximum voltage and is reducing the current. No problem, this is a normal condition.
Ammeter reads less than selected charge rate when charging a discharged battery Extension cord is too long or wire gauge is too small. Use a shorter or heavier gauge extension cord.
Weak cell or sulfated plate in battery. A sulfated battery will eventually take a normal charge if left connected. If the battery will not take a charge, have it checked.
Battery is only partially discharged. Continue to charge the battery.
The charger is making an audible clicking sound. Circuit breaker is cycling. The settings may be wrong. Check the charger settings.
Battery is defective. Have the battery checked.
Shorted battery cables or clips. Circuit breaker cycles when current draw is too high. Check for shorted cables or clips and replace if necessary.
Severely discharged battery, but otherwise it is a good battery. 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.
Reverse connections at battery. Shut the charger off and correct the lead connections.
Charger makes a loud buzz or hum. Transformer laminations vibrate (buzz). No problem, this is a normal condition.
Shorted Diode Assembly or Output Rectifier Assembly (hum). Have charger checked by a qualified technician.
Short or no start cycle when cranking engine. Drawing more than the Engine Start Rate. Crank time varies with the amount of current drawn. If cranking draws more than the Engine Start Rate, crank time may be less than 3 seconds.
Failure to wait 4 minutes (240 seconds) between cranks. Wait 4 minutes of rest time before the next crank to allow the battery and charger to cool down.
Clips are not making a good connection. Check for poor connection at battery and frame.
AC cord and/or extension cord is loose. Check power cord and extension cord for loose fitting plug.
No power at receptacle. Check for open fuse or circuit breaker supplying AC outlet.
The charger may be overheated. The thermal protector may have tripped and needs a little longer to close. Make sure the charger vents are not blocked. Wait and try again.
Battery may be severely discharged. On a severely discharged battery, charge for 10 to 15 minutes in the highest manual rate to help assist in cranking.
Schumacher User Manual Link


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.
