Why is there no reading on the ammeter of my Schumacher Electric Battery Charger?

  If your Schumacher Electric Battery Charger's ammeter shows no reading, several factors could be at play. First, ensure the charger is properly plugged into a functioning AC outlet and that the outlet has power by checking the fuse or circuit breaker. Next, verify that the clips are making a solid connection to the battery and frame, ensuring the connection points are clean, and rocking the clips back and forth. Also, check that the connections are not reversed; if they are, unplug the charger and reverse them. The battery itself might be defective and unable to accept a charge, in which case you should have it checked. Finally, note that the ammeter may not show activity if you are using the 2 amp charge rate.

Why does my Schumacher Electric SE-4225 Battery Charger make a clicking sound?

  If your Schumacher Electric Battery Charger is making a clicking sound, it could be due to several reasons. The circuit breaker might be cycling, indicating incorrect settings, so check the charger settings. The battery may be defective and should be checked. There might be shorted battery cables or clips, which should be inspected and replaced if necessary. A severely discharged, but otherwise good, battery may also cause this; allow charging to continue until the battery recovers sufficiently. Lastly, reverse connections at the battery can cause this issue; turn off the charger and correct the lead connections.

  If the ammeter reading on your Schumacher Electric Battery Charger remains high, it could be because the battery is severely discharged; in this case, continue charging it for two more hours. Alternatively, you might be using the wrong battery voltage. Make sure you are using a 12-volt, lead-acid battery.

Why does the ammeter read less than selected charge rate on my Schumacher Electric SE-4225 Battery Charger?
- D
  Dr. Misty Brown MDAug 14, 2025
  If the ammeter on your Schumacher Electric Battery Charger reads less than the selected charge rate while charging a discharged battery, the extension cord might be too long or have too small a wire gauge; try using a shorter or heavier gauge extension cord. It's also possible that the battery has a weak cell or sulfated plate; a sulfated battery may eventually take a normal charge if left connected. Lastly, the battery might only be partially discharged, in which case you should continue charging it.

  If your Schumacher Electric Battery Charger does not turn on when properly connected, the AC outlet may be dead. Check the fuse or circuit breaker supplying the AC outlet. There may also be a poor electrical connection. Check the power cord and extension cord for a loose-fitting plug.

  If your Schumacher Electric Battery Charger is on but not charging the connected battery, the clips might not be making a good connection. Check for a poor connection at the battery and frame, ensure the connecting points are clean, and rock the clips back and forth for a better connection.
