We’ve all heard the noise – a horrid metallic grinding as the car’s starter tries to engage a running engine.  What’s it mean when you hear that noise and the motor isn’t running?

It could mean the starter is going bad.  More often, it means there is a damaged spot on the ring gear, the big gear on the motor that the starter engages to turn over the engine.
