Each time someone reports a problem with Light Speed Engineering electronic ignition system I look back through my notes to remind myself how everything is connected. Each time I wish I had a diagram that showed all the modules and their interconnection. I have never seen one so I decided to create it myself.
The attached PDF is a rough first draft. Review and comments appreciated. Hopefully the final version will be useful to all owners and maintainers of CubCrafters aircraft that use this ignition system.
