Rob..
What coil would you reccomend for the French 2cv TCI board? A standard CDI type coil has too low resistance to function correctly with a typical value of 3 to 4 ohms or less...making the system draw a huge amount of current, reducing efficiency. I have a rather large coil I used in testing that was designed for ignition systems with points. It typically has 5 ohms of resistance and functions as expected, but weighs almost a pound!
