- This triggering method
has been superceded by the Mini Sensor
Speed Engineering, LLC has developed three different devices to send
crankshaft position information to the Plasma CD ignition
systems. One method uses the Hall Effect Module which is
installed in the accessory case and senses crank shaft position by
means of the non-impulse magneto drive gear. The second mechanism is the Mini Sensor described on the Mini
Sensor page located here. The old
style triggering mechanism is
the Direct Crank Sensor system described here.
Direct Crank Sensor triggering mechanism is versatile and will work
with most aircraft engines.
engines and all Continental engines must use the Direct Crank Sensor
or the Mini Sensor.
crank sensor circuit board has two completely independent triggering
circuits if it is used for dual Plasma CDI applications.
On single installations only the outer set of sensors and
associated wiring harness is installed.
