On the cusp of being a grand master.

I actually have a question for you. Can you suggest something I could read that would give me a basic understanding of electronics. I figure that is an area that would be suited to my talents--more cerebral and finesse. And lord knows, there are certainly lots of annoying electrical issues with e34s. And yes I have a Bentley that would guide me though specifics, but I am taking a guide to basic theory. Thanks.
