  If your Schumacher Electric Battery Charger shows no reading on the ammeter, several issues could be the cause. First, ensure the charger is plugged into a working AC outlet and that there is power at the receptacle by checking the fuse or circuit breaker. Also, check the clips for a good connection to the battery and frame, ensuring the connection points are clean. Rock the clips back and forth to improve the connection. It's also possible the connections are reversed; if so, unplug the charger and reverse the clips. Finally, the battery itself may be defective and unable to accept a charge, in which case you should have the battery checked.

Why is my Schumacher Electric SE-1072 Battery Charger making a clicking sound?
- J
  Jordan NelsonAug 2, 2025
  An audible clicking sound from your Schumacher Electric Battery Charger can be caused by several factors. The circuit breaker might be cycling, so check the charger settings. The battery could be defective, in which case you should have it checked. Shorted battery cables or clips could also be the problem; inspect them and replace if necessary. If the battery is severely discharged but otherwise good, allow charging to continue until it recovers sufficiently, but if it continues for more than 20 minutes, stop charging and have the battery checked. Lastly, reverse connections at the battery can cause this; shut off the charger and correct the lead connections.

  Anthony BakerAug 7, 2025
  If the ammeter reading stays high on your Schumacher Electric Battery Charger, it could be due to a severely discharged battery; in this case, continue charging the battery for two more hours. Alternatively, the battery voltage may be incorrect; verify that the voltage settings on the charger are correct.

How to fix a Schumacher Electric SE-1072 that will not turn on?

  Derrick EvansAug 13, 2025
  If your Schumacher Electric Battery Charger will not turn on when properly connected, the AC outlet may be dead; check for an open fuse or circuit breaker supplying the outlet. Another possibility is a poor electrical connection; check the power cord and any extension cords for loose-fitting plugs.

What to do if ammeter reads less than selected charge rate on Schumacher Electric Battery Charger?

  Mark HoganAug 20, 2025
  If the ammeter reads less than the selected charge rate when charging a discharged battery with your Schumacher Electric Battery Charger, the extension cord may be too long or the wire gauge too small; use a shorter or heavier gauge extension cord. A weak cell or sulfated plate in the battery could also be the cause; a sulfated battery will eventually take a normal charge if left connected. It's also possible that the battery is only partially discharged, so continue to charge the battery.
