The question arose, and after about 3 days of searching through Help/icm/coil/no spark issues, i received no answer.

To trigger a coil inside of the distributor, what kind of signal does the ICM send to the coil?
Is it 3.3v? 5v? 1v? 12v? Ground?

 

Below is the circut, and the one i am interested in.
This is the circut B(coil) to 2(ICM)

 

anyone?

 

Ground -- hence explaining why the Wht/Blu wire terminal of the coil is labeled (-).

This thread shows you how to test whether the ICM is providing proper ground to the coil.

 

i was considering using the ICM as a trigger for a coil on plug setup using the cap/rotor to select the appropriate coil.

 

Okay
