Alternator problem

My alternator light came on in my 2004 Boxster S. While the car was running I measured 14.5 volts at the battery and when the car was off I measured over 12 volts. The car was running fine. I went ahead and had the alternator rebuilt and the shop refreshed everything and installed a new regulator. I put everything back together and The light still comes on. I'm not sure how to diagnose further. Any suggestions?
