I have my scope set on ac coupling across the battery terminals. I’m trying to convince a shop this thing has major mechanical issues. There not buying it saying they can’t see it having issues. Let me know what you guys think. I didn’t have time to sync a coil or anything just got 1 channel going
Here is a pic of the results.

I love doing those chains. I'd do a set every day if I could. Maybe two if I got really good!
Let these goons ignition switch it if it makes them feel better. :silly:
