| 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. |
