Troubleshooting
Performance problems often result from little things that you can fix yourself. Please read through this table for a possible solution if a problem occurs. 
PROBLEM POSSIBLE CAUSE SOLUTION/REASONS
No ammeter reading. Clamps not making good connection. Check for poor connection at battery. Make sure clamps and posts are clean.
2-amp charge rate. Ammeter needle will indicate little activity at the 2-amp charge rate. 
No AC power reaching charger. Check AC outlet and extension cords for loose fitting plug. 
Check for open fuse or circuit breaker supplying AC outlet.
Circuit breaker in charger cycles on and off with a clicking sound. Shorted battery clamps. Separate the clamps.
Circuit breaker cycles when current draw is too high.
Check for worn cables and replace if needed.
 
Shorted battery. Have a Sears Service Center test the battery.
Charger leads reversed on battery. Correct connections.
Ammeter reads less than selected charge rate when charging. Extension cord too long or gauge too small. Use shorter or heavier extension cord.
Battery has weak cell or sulfated plate. Sulfated battery will eventually take a normal charge if left connected. If the battery will not take a charge, have it tested by a Sears Service Center.
Battery is partially charged. Continue charging battery.
Charger makes a loud buzz or hum. Transformer laminations vibrate (buzz). Continue charging. Buzz is not abnormal.
Shorted diode (hum). Have charger tested by a Sears Service Center.
Short start cycle when cranking engine. Drawing more than 50 amps for a period equal to or less than 10 seconds. Crank time varies with the amount of current drawn from the charger. If cranking draws more than 50 amps, crank time may be less than 10 seconds.
Failure to wait for 4 minutes (240 seconds) between cranks. Wait 4 minutes before next crank.
