1986 Crusader alternator ?

As I was reinstalling the alternator on a 1986 Crusader 454 I broke off what looks like a condenser about 1 inch long and 1/2 inch diameter. I though, whatever it does it probably has to be grounded or it won't work. I looked at the other alternator on my twin engine tiara and it is broken as well, so I thought maybe it is just a noise suppressor and may have nothing to do with alternator output. It is attached to the REG term and the wire reattaches to the same terminal. Is that a noise suppressor or something that needs fixed or the alternator wont work?
 
The capacitor is there for noise suppression, as you suspected. if it looks like the same part used with a point type distributor (silver can with a single lead coming out of one end, on the can's axis) it is a capacitor.

Yes, it has to be grounded in order to function. The alternator should provide its charging function without the capacitor...the output just won't be "RFI clean" (it will be noisy).
