I would like to spend some serious time doing a qualitative analysis of the EMI that is probably going on in my engine bay. I've been searching Google for some write ups that might help me get started, but everything seems to be quick marketing blurbs for every electronics company on the planet. Does anyone have some links or books or anything that might help me?

Here is how I would like to approach the problem:
1. Evaluate my current situation.
2. Identify the sources.
3. Implement effective corrective measures.
4. Judge the effectiveness of my efforts.

This is probably over the top, but being the son of an engineer makes me think this way. (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif)

So give me your best links and books regarding identifying and dealing with EMI, please.

I'm wondering if I can use my oscilloscope for step 1. But I'm not sure if I should use it in series, in parallel, or just ground to the negative battery post and probe wires. (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)
