What to do if Schumacher Battery Charger is on but not charging?
If your Schumacher Battery Charger is on but not charging, the clamps may not be making a good connection. Check the connections at the battery and frame, ensure the connecting points are clean, and rock the clamps back and forth to improve the connection.
Why Schumacher SpeedCharge SC-1200A Battery Charger will not turn on?
If your Schumacher Battery Charger doesn't turn on when properly connected, the AC outlet may be dead, or there may be a poor electrical connection. Check the fuse or circuit breaker supplying the AC outlet. Also, inspect the power cord and any extension cords for loose plugs.
Why is the connected red light blinking on my Schumacher SpeedCharge SC-1200A Battery Charger?
If the Connected (red) light is blinking on your Schumacher Battery Charger (models SC-600A, SSC-1500A, SC-1200A), the charger may be in abort mode. This can happen if the battery is faulty or if it did not reach full charge within 48 hours, possibly due to a very large battery or a bank of batteries. To resolve this, reset the charger by unplugging it, then select the desired CHARGE RATE and battery type again, if necessary.
What to do if the charged light turns on too soon on Schumacher SpeedCharge SC-1200A Battery Charger?
If the CHARGED (green) light on your Schumacher Battery Charger turns on quickly after connecting the battery, the battery may already be fully or recently charged. Alternatively, the battery could be faulty (sulfated). If the battery is in a vehicle, turn on the headlights for a few minutes to reduce the battery voltage and try charging again. You can also try a lower CHARGE RATE. A sulfated battery may eventually accept a charge, so continue charging for a few hours, watching for the CHARGING (yellow) LED to blink. If it doesn't, have the battery checked.
How to fix Schumacher SpeedCharge SC-1200A Battery Charger when connected light is not on?
If the Connected (red) light is not on for models SC-600A, SSC-1500A, and SC-1200A, or the CHECK (red) light is not on for models SC-1000A and SSC-1000A on your Schumacher Battery Charger, it may be due to incorrect battery connection, reversed connection, or the battery voltage being less than one volt. Check for poor connection to the battery and frame, ensuring connection points are clean. Rock the clips back and forth for a better connection. Correct the connection if it's reversed. If the voltage is too low, replace the battery or use a manual charger to bring it above one volt.
What to do if indicator lights are erratic on Schumacher Battery Charger?
