Lucas did at one point use a "ballast" resistor that was wired in series with the coil, this just added more complexity and something additional to fail. I don’t remember seeing this setup on Alpines but it would have been used in the 1967-70 period. Best is to use a standard Lucas coil and no resistor. Not being a fan of "the Prince of Darkness" (as Lucas is sometimes jokingly called) I use a coil for a 1967 Volkswagen or a Petronix coil for a British car. I could write a book about my experience with Joseph Lucas products… most of which is very funny in hindsight.
