Mopar Electronic Pickup Polarity and Rotor Phase

Yes, that is what was on scope. Think how that follow edge trigger trigger could directly used to drive an ignition IGBT. It is bit more complicated, there needs to be dwell control, to turn transistor on earlier as RPM increases, and current limit, serving to replace ballast resistor.

I have a cheap timing light, added BNC connector to clamp-on leads, use BNC to BNC cable with scope, to see timing light trigger.

Other methods use 50 Ohm 20 W resistor instead of ignition coil, trigger will be when what would have been coil (-) goes high.

Don't try hooking normal scope probe to coil (-). Only use 1kV or more probe for that.
