Problem: The battery charger won't charge the car or heaves a high amp draw. 

Solution: There are several reasons why this could be happening, but in most cases, it's because the battery is not being charged at all. Check to make sure that there are no loose connections or any other problem with your car's electrical system before using the charger. 


Problem: The charger seems to take too much time to recharge the battery.

Problem: The charger won't turn on when plugged in.

Solution: The Schumacher battery charger is not working properly, and you may need to replace your main power regulator board. Double-check that the connection is secure and that your battery has enough charge before replacing a part.

Allow the device up to 20 minutes before taking any actions depending on what type of noise persists, but if the sounds continue with new batteries in place then there may be something wrong with your connections.
