I haven't been back to work on my car yet this week. so it goes as a corporate jet pilot ,but I am flying to California for the first part of the pebble beach concours this week
Anyway I think I'm going pull the alternator off and have it tested when I get back. while I've got it off, I will check and clean all the connections on the alternator and starter.
by the way are there any Porsche guys in the Chicago area? I am in the process of moving our jet there.
