OPERATION
The signal generator used with this system, is a small magneto which produces a signal that is processed by the ECU to determine the exact time to open the coil primary circuit and produce a high voltage.

CONSTRUCTION
This system consists of the distributor, ignition switch, ignition coil, ECU igniter and spark plugs. Primary circuit current is controlled by the ECU igniter in response to timing signals produced by the distributor pick up. The distributor consists of the power distribution section, signal generator, ECU igniter, advance mechanism and drive gear section.
