Quoted from Dewey68:

Is that to help clean up the signal? It's already clipped on one side. That's why I was curious what it was. I'll leave it as it is for now.

Yes, the cap is to extend the signal pulse on quick hits. If you find your (target) switches are not registering quick hits, replacing the cap will help improve that. Older original caps sometimes become shorted and fail, hence the common sight of them being cut. Once they are cut and the problem cured, they should be replaced - but you will often see them just left cut.

Quoted from Dewey68:

The signal striped wire going to the coil lug should be the ground side, correct? If I ground that side it should fire.
I'll try the flipper button in the coil test.

Another way to determine which side is ground is to look the diode across the coils that have them. The striped side (cathode) of the diode is attached to the power supply side of the coil - grounding the opposite side fires the coil.
