Pulsating Dash and head Lights

Santa Rosa Beach, 

The headlights and dash light pulsate every time I operate the vehicle - day or night.  I had an unrelated issue last year and as a result the alternator was replaced by a well respected Porsche service shop in Clearwater Florida.  The pulsating was first noticed soon after the alternator was replaced.  I returned the vehicle to the shop and they removed and tested the alternator and it was found to be in good condition.  No explanation for the pulsating was offered other than to say..."let's keep an eye on the issue".  I have subsequently moved to the panhandle of Florida and have again taken the vehicle to a known and respected porsche repair shop where they also tested the alternator and again found it to be functioning correctly.  But...the pulsating continues with no other problems or issues with the vehicle identified. If anyone has any thoughts it would be most appreciatied.
