engine stand wiring harness

That's normal, in "run" going through the coil resistor. I understood you are using a Mopar IGN switch. You should have a separate wire from the terminal in the diagram marked as "brown bypass" runs right to the + side of the coil. If the rear of your switch looks different or is not marked, post a photo.

So that is what puts battery volt. on the coil during crank.
