1974 Dart 318 crank, but no start (Solved)

You have a problem with the circuit or you are not checking it right. Full battery voltage on the negative side means that there is an open circuit/ loss of connection from coil negative to the module and possibly ground.

Unplug the ICM connector and with the key in run check for voltage at the pin for the negative coil wire. You should have 12 volts there, because you just created an open circuit at the connector, but because it's giving full battery voltage, that means that there is no break in the wire from the coil to the ICM.
Yup, I knew it was gonna be something stupid, most likely my fault, and was correct. Got home from work, popped connector off, tested voltage, nadda at ICM side of wire from - side of coil. Thought maybe the new harness I bought was bad, but thought I better check my 1 connection on that wire, the eyelet....AAW kit came with black insulators to cover the crimp connections, as I slid it back, the wire fell out, leaving the eyelet and a few strands of wire connected to coil.....stripped wire, crimped on a new eyelet, bolted back on the coil, instantly got my reduced voltage thru ballast, and the damn car started! So now I have a bunch of backup ignition parts, lol. Thank you for your help, If you hadn't said to check the unplugged side of wiring, dunno how much longer this would have stumped me. Now that it runs, I can move forward, Thanks again all that chimed in.
