No spark on my 84 Ram.

Well it isn't the wiring to the coil. I went through the trouble of cutting out the plug and the voltage didn't change. Only then did I decide to check what my Dart does and it only see's 4 volts in run, and 5.25 volts while cranking. It fires off with no trouble with less voltage. Something I did find. When turning the key from the "run" position to the "off" position the truck will huff sometimes, like it is sparking. I verified this with my timing light with the mag clipped onto the coil wire. When I click from "run" to "off" it will give me a shot of light every time.

To complicate things I was trying to figure out the coil thing and I jumped a wire from the + of the battery to the + of the coil, then started cranking (I found the above problem with my timing light before this). Didn't make any difference, although afterwords I remembered a coil reads as a short, so might have fried my ignition box.
