I'm just wondering if somebody can clear up what and why distributors need breaker points. I understand that it is necessary to drop the voltage to the outer coil, which produces a magnetic field due to the different lengths of the coils so the inner coil can create a large voltage spike. How do systems that don't contain the contact breaker work? What about when you move the position of the distributor cap, does it also move the position of the breaker points? Thanks for your help.
