For general ignition intro info.
 Troubleshooting + Repairing Automotive Ignition Systems
     By Andrew Stevens  (old, probably outa print) library might have thou
 The Drs Guide to Optimizing your Ignition System
     Dr Jacobs   available from Jacobs Electronics  Kind of an ad for his
prducts    but does have good entry level info.
