Tracy,
Thanks, I was researching this on the web and someone stated that there were 2 pulses per revolution

It is the yellow wire on the trailing coil assembly that is the tach drive signal. I never looked at the signal but I used it to drive an analog car tach setup for a 4 cyl. Engine on my first installation.

I would like to use the tach signal from the lead igniter I believe is present on the yellow with blue tracer wire.
Does anyone know what this signal is? Is it a 12volt pulse? How many pulses would represent a complete revolution?
Thanks for any help
