the famous blue wire … This wire commonly called “kill wire” is for switching the system off by shortcircuiting the internal capacitor. This function is needed as magneto based CDI systems would otherwise run until you run out of petrol (gas).
What is inside a CDI box?
A typical CDI module consists of a small transformer, a charging circuit, a triggering circuit and a main capacitor. First, the system voltage is raised to 250 to 600 volts by a power supply inside the CDI module. Then, the electric current flows to the charging circuit and charges the capacitor.
