Starter is not cranking?

I have a 68 Dart w/ a 340. I was trying to fix some wiring issues and the msd blaster 2 coil accidentally took power to the negative and next thing I know car won't crank. I don't know If I just missed a wire somewhere or I actually killed something on my car.

This is what happens. I turn the key and the starter relay by the battery clicks but it won't engage the starter. Is there a way I can manually connect the terminals on the starter to power/ground and see if that's the issue or if its the relay that's killed.
