what does an ignition control module actually do?

It controls th ignition coil's firing time. The ignition control module is the heart of an automobile's ignition system. It regulates spark generation within the engine. The ignition control module relies on the car battery to provide the 'spark' that sets the ignition system in motion. The ignition control module is normally located inside or near the car's distributor and is usually coated with insulating compounds to protect its internal electronic components.

Ok so the ignition control module has absolutely nothing to do with the charging system. Understood. I have replaced Alternator, starter relay, and battery. I think this was a problem before that the only solution was to route a wire from the button to the ignition module, to make it charge. So here I am clueless in Seattle, thinking WTF.
