Never believe those clerks at auto parts stores, the voltage regulator is internal to alternator. Check fusible link going to alternator. Or pull alternator off and have the auto parts test it if it is good and fusible link is good off or starter or getting battery voltage at large wire on alternator. Then have a mechanic scan for codes because it may be a CAN/BUS problem.
