Are you ready for a real weird one? Random NO spark from a MP electronic ignition system despite numerous parts swapped around...

I always attribute a minor spark when connecting a battery, to radio memory or clock

I think that I found it. The stereo constant power wire is on the unfused side of the fuse panel. This is why pulling the fuses didn’t help and the issue was narrowed down to the one unfused wire on the relay. Now I need to reroute a couple of terminals since in error, I have a few things attached to the wrong side of the fuses.
Heck yeah!
The battery itself already loses charge but the draw of constant power only sped it up.
I would not have looked this deep if not for Randy, 1 Wild R/T.
Thanks!

Big shout out to 1 Wild R/T and the others helping Kern. When this is figured out o think a “sticky” is in order to help debug electrical issues but that’s me
