Why is my car battery charger not powering on?

Motor Vehicle Maintenance & Repair Asked by Patrick young on December 28, 2020

I’ve had my car battery charger for about six months and, just recently, it won’t power on. When I connect it to the battery and the mains, the orange light comes on but there is no low humming noise that means its charging. Usually when it was working, I connect it to the battery and the mains, the light orange light comes on and the unit hums because its powered on. Now the orange light comes on and stays on but there is no power sound. Can anyone help?

One Answer

most probably, your charger has a blown fuse. replace the fuse with a known good one. use multimeter and safely check for the voltage across output, i.e. +ve and -ve connectors of your charger.
