to test it put a volt meter across the batt terminals and it should read about 14.5 at 5k rpms and about 13 at 2500. to check the rotor put a volt meter on the ohm settings and touch inbetween the slip rings and it should be between 4-6ohms. anything more or less and its bad. check and make sure the brushes arnt near their scribe marks. you can then test the regulator rectifier. if you want to do that then let me know lol. i have an entire diagnostic flow chart with directions and everything on how to diagnose the charging system
