87 prelude 1.8L carb model with Manual Trannie.

So I decided to have another look at the
alternator and other stuff today on my
girlfriends car. The belt actually look a
little suspect, so I replaced it, and it seems
to have fixed the problem of the charge light.

My question is, could the charging problem be an
intermittent problem? Or was it just a glazed
belt?
