Had the belts changed, even the pulley as it looked a bit ‘polished’ but my alternator is still very whiney. It’s not too noticeable during the day, but at night when the lights are on, it gets considerably louder, and even worse if you press down on the electric windows. To me, it sounds like it’s being overworked, or even strained. My mechanic said the last thing to do was possibly change it, but there could be other factors as to why it’s being overworked. Any ideas?

Thanks in advance.
