understanding ignition systems

[Anthony]

Aside from the spark igniting the fuel I know nothing about how the rest of it works.  Can anyone suggest a site that explains  triumph twin ignition systems?  What the coil and magnito does and such?  How the charging system works, that sort of thing?

This website could be of some use?:

Although not specifically for Triumphs these sites have a lot of basic information that goes a long way to understanding the way motorcycles work.
