Thought I'd start a separate thread to help Hal with his alternator wiring. I'm sorry I couldn't remember the details at Carlisle, but I used the following info to wire my Geo alternator on the Birkin. Not sure what type of alternator the Caterham uses, but the wiring should be similar. Maybe some of you Caterham owners can jump in...

It's for an airplane, but I thought the description and drawing was pretty good.
