Closing the loop on this issue for those following....... Today my new Valeo alternator and belts from max @ oembimmerparts were installed by my indy. This appears to have fixed the problem. The alternator charged 14v at engine start, no lights. The problem was either the alternator or the regulator. I put my money on the regulator as being the culprit. So this faulty alternator resulted in delayed charging during the first start of the day, occasional idiot lights on the dash and never threw a fault code that I could read on my Creader VI.

So at the end of the day it cost $419.00 for a new alternator, $34.00 for two new belts and $255.00 in labor totalling $708.00. Thanks to all who shared their advice and troubleshooting procedures.
