  Janice JohnsonAug 19, 2025
  If your Schumacher Battery Charger won't turn on even when properly connected, the issue might stem from a few sources. The AC outlet could be dead due to an open fuse or circuit breaker, so check that first. Also, inspect the power cord and any extension cords for loose connections. Lastly, the battery itself might be defective, so consider having it checked by a professional.
