If your Schumacher Electric Battery Charger won't turn on, the AC outlet may be dead. Check for an open fuse or circuit breaker supplying the AC outlet. Also, check the power cord and extension cord for a loose-fitting plug.
Why is my Schumacher Electric SC-10030A making a clicking sound?
The clicking sound from your Schumacher Electric Battery Charger indicates the circuit breaker is cycling. This can occur if the settings are incorrect, so check them. The battery may not be accepting a charge or the current draw is too high. Inspect the cables and clamps for shorts and replace if necessary. If charging continues for more than 20 minutes, stop and have the battery checked. Shut off the charger and correct the lead connections.
What to do if my Schumacher Electric Battery Charger is on but not charging?
If your Schumacher Electric Battery Charger is on but not charging, the clamps may 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 clamps back and forth for a better connection.
Why does my Schumacher Electric Battery Charger make a loud buzzing or humming noise?
A loud buzz from your Schumacher Electric Battery Charger is typically normal, caused by transformer laminations vibrating. A humming sound could indicate a shorted diode assembly or output rectifier assembly. Have the charger checked by a qualified technician.
What to do if my Schumacher Electric Battery Charger's green light turns on too quickly?
If the green Charged LED lights quickly on your Schumacher Electric Battery Charger, the battery may already be fully or recently charged, causing a high voltage reading. If the battery is in a vehicle, turn the headlights on for a few minutes to reduce the battery voltage and try charging again. You can also reset the charger by briefly unplugging it or disconnecting the negative battery clip, then re-select the desired rate (SMALL or LARGE BATTERY) and battery type.
What does it mean if the indicator lights are erratic on my Schumacher Electric SC-10030A Battery Charger?
Erratic indicator lights on your Schumacher Electric Battery Charger may indicate accidental activation of a special diagnostic mode. Ensure nothing is touching the control panel, then unplug the charger and plug it in again.
Why does the digital display flash on my Schumacher Electric SC-10030A?
If the digital display on your Schumacher Electric Battery Charger flashes before the battery is fully charged, the incorrect battery type may have been selected. Reset the charger by briefly unplugging it or disconnecting the negative battery clamp. Then, select the desired rate (SMALL or LARGE BATTERY) and battery type again, if necessary.
Why is my car having a short start cycle with the Schumacher Electric SC-10030A?
A short start cycle when cranking the engine with your Schumacher Electric Battery Charger suggests it's drawing more than 100 amps. Crank time varies with the amount of current drawn. Wait 3 minutes before the next crank. Check for poor connections at the battery and frame, and ensure the power cord and extension cord have a snug fit. Also, check for an open fuse or circuit breaker at the AC outlet. For a severely discharged battery, charge for 10 to 15 minutes at the large battery rate.
Why don't my Schumacher Electric Battery Charger clips spark?
The lack of spark from your Schumacher Electric Battery Charger clips when touched together is normal. The charger is equipped with an auto-start feature.
