Instructions / Assembly

– 58 –
(3) At higher engine revolution, the advancing control circuit operates at the ignition timing to run the base
current I
5 to turn the signal transistor B "ON" allowing the current I1 to bypass as current I6.
At this moment the power transistor turns "OFF" and the current I
2 is abruptly shut resulting in the high
voltage generated in the secondary coil which produces sparks at the spark plug.
The operating timing of the advancing control circuit advances in accordance with the increase of engine
speed resulting in the advancing of ignition timing.
