The principle of the circuit The motorcycle electronic ignition circuit is composed of the resistors R1-R3, the capacitors C1 and C2, the diodes VD1-VD3, the thyristor VT and the magnetor charging coil W1, the control coil W2, the ignition coil T, the circuit is as shown in figure 7-138. The output AC of the magnetor winding W1 is half-wave rectified by VD3 to charge the C1. Components selection The R1-R3 use the 1/4W metal film resistor.The C1 uses the 400V CBB capacitor or the polyester capacitor; C2 uses the 5OV aluminum electrolytic capacitor.The VD1-VD3 use the 1N4007 silicon rectifier diode.The VT uses the 2P4M(2A, 400V) thyristor.
