What to do if my Schumacher SC1357 Battery Charger won't turn on?
If your Schumacher Battery Charger won't turn on when properly connected, there are several potential causes. First, the AC outlet may be dead; check for an open fuse or circuit breaker. Second, there might be a poor electrical connection; inspect the power cord and extension cord for a loose-fitting plug. Finally, the battery itself could be defective and should be checked.
Why is the red LED lit on my Schumacher SC1357 Battery Charger?
The red LED on your Schumacher Battery Charger can light up for multiple reasons: * The battery voltage is still below 10V (for a 12V battery) or 5V (for a 6V battery) after 2 hours of charging, which may indicate a defective battery. Ensure no loads are on the battery; if there are, remove them. If not, have the battery checked or replaced. * In maintain mode, the output current exceeds 1.5A for 12 hours, suggesting the battery may be defective. Have the battery checked or replaced. * Desulfation was unsuccessful, indicating a potentially defective battery that should be checked or replaced. * Lack of progress is detected and battery voltage is below 14.2V (for a 12V battery) or 7.1V (for a 6V battery), suggesting a defective battery. * The battery’s initial voltage is below 12...
