alternator rectifier smoothing

I was wondering if the average GM alternater uses a capacitor to smooth the output of the rectifier. Is a fully rectified wave enough for charging the battery or does it need to be smoothed out?

Re: alternator rectifier smoothing

I'm not sure about the GM stuff, although they never miss an opportunity to save 2 cents, so I guess they're just rectified.

I think most alternators are simply a fully rectified wave, but I'm no expert.

I would agree. I have rebuilt many GM alternators, and none use a capacitor.
