David,
I concur with the others about the value of Bob Nuckolls AEROELECTRIC CONNECTION book. Another recommendation is FAA AC43.13-1B, which can be downloaded for free. It's done chapter by chapter, as the entire document is over 400 pages. You could download just the electrical portion. I suggest getting the entire thing, as it's LOADED with good info. See

I've also got PDF versions of the FAA study books for aircraft mechanics. They have useful info to.I sent you a private message regarding sending those to you.
