it is not uncommon to get a bad alternator rebuilt or new. many rebuilt units do not get new commutators or slip rings the unit should be under warranty so try another one. i have better luck having my old broke ones rebuilt by a local guy than getting a rebuild from a parts store that gets units from mexico
