Are you saying that an alternator doesn't need a capacitor?
Also, that doesn't answer my question about whether or not I
need to take the alternator apart to check the diodes in the capacitor.

The word you are looking for is Rectifier.

I don't know if a bad capaciter could cause a charging issue (like a short circuit) but it could be unplugged to see what happens.
I don't recall my Alternator having a Capacitor.
