Do you know what machine I have? It doesn’t trigger like a Sun does. The machine gets triggered from the SOURCE, so on points or ANY system that acts like points like a Unilite the machine gets triggered by the “points” or in the case of the Unilite it triggers off the green wire, which is just like triggering points.
So the machine sees exactly what the trigger is doing whether the box is hooked up or not. I can actually test most ignition boxes with just the machine and nothing else. You can’t do that with a Sun or any other machine Ive ever seen, with the exception of those King brand machines and Ive only seen a few pictures of those.
So when you see the timing going backwards in the video thats exactly what it’s doing and it’s the box doing it.
