Check the Factory Service Manual (FSM).  There are brushes, which wear out, in the alternator.  The Rectifier/Regulator is somewhat difficult to test out of circuit.  Essentially, check the resistance of the windings on the alternator parts, as per the FSM.  Once you have AC coming out of the Alternator (yellow wires), then check to see what, if anything, is coming out of the Regulator, as per the FSM.  Always have the battery in the circuit!  Never run the bike without a battery installed!!!

Stators, and rotors can be had, or rebuilt -- they are not rare items.  I would suggest holding onto your money, until you know what you need -- then buy the necessary parts, and get it running.  Cheers!
