Ever since I accidentally let my battery drain out, what I assume is my starter has been making a knocking-type noise upon startup. Last night she wouldn't start - there was a noise like a bicycle wheel going round very fast with a card in the spoke (coming from the starter, again). The noise is comparatively quiet compared to how loud the starter was. I'm guessing the thing finally kicked it. But I have no experience with starters, and wanted to get some confirmation on that fact before I stop by NAPA. Anyone have any info they can share? Thanks a million!
