RPM Ignition Limiter Functions

NOTE: The CDI box reads the RPM signal from the stator. The CDI box acts as a limiter by retarding the
ignition timing if RPM reaches the specified limit. In reverse gear, the CDI box retards ignition timing and
limits RPM once it receives a ground path from the transmission switch dark blue (DB) wire indicating the
vehicle is in reverse. The CDI box can also receive a ground path from the ETC switch causing the CDI box to
retard timing and limit RPM if the throttle cable becomes slack or stuck.
