Mopar Electronic Pickup Polarity and Rotor Phase

Mattax said
When I find it I'll put a link here.

Maybe this was it. Refering to using a 4 pin HEI module with a points distributor:
Yes that works but it works backward, it fires when the points close not open, so you will want to re-clock the rotor, and...
It is customary to instead use approx a 40 ohm resistor. This runs enough current through the points to keep them clean.
MSD boxes use 40 ohms, and so did delta before them.
TFI fires "going high", like points do, opposite of the GM , so using the TFI module is a lot easier.

The lower trigger trace was generated using ncv1124 variable reluctance interface.

So the scope is picking up just one signal. It's clipped on to the magnetic pickup leads.
The lower trace is that signal run as modified by the interface so it looks like (works like) a falling edge trigger ECU .
yes?
