Paul,

 

Do you know what the tach signal coming off of the trailing igniter yellow wire looks like ( voltage frequency range)?

 

I think you get 2 pulses per rev.

 

I would like to condition the signal for the arduino engine monitor.

 

Thanks for any help

Two pulses per rev of the Crank Angle Sensor. However the Crank Angle Sensor is geared
to the e-shaft and it runs at half E-shaft speed.
There  another sensor in there that puts out 12 pulses per E-shaft rotation.

Press the roll pin out of the gear and chuck it in a drill press.
Use an O-scope to look at the wires.
