Here is a test on the box going in my car. It’s wired up exactly as it will be in the car. I forgot I recorded this, as I had forgotten if I even tested this box and was going to pull the box back off the car just to test it.
This just happens to be a very good box.
If you watch it I have the nasty habit of using distributor and crank degrees interchangeably and that’s bad.
Every tic mark is 1 distributor degree or two crank degrees regardless of how I screw it up.
But the box does retard. If someone really wants to throw up in their mouth I can do a test with the orange box hanging on the wall and you can see what massive, early retard looks like. I think that box retards at least 8 degrees by 7k or something. It’s pretty nasty.
I can't see it in the in the video. Where does your distributor machine hook up to the ignition system? How is the rest of your set hooked up. Looks like you have a round something Where all the secondary spark occurs?
