I did emery cloth the points just a bit to clean them up but other than that I've done nothing today. I pull the main wire from the top of the distributor and hold it close to ground while cranking and there is no spark still yet. I'm thinking my coil just took a dump.
DON'T start replacing parts until you find out what is wrong. Use a voltmeter and a wiring diagram and go through it step-by-step. If you start throwing parts at it you will introduce issues and it will make it much harder to troubleshoot. 6V on both side of the coil is normal. The point side of the coil goes to 0v only when points are closed and ignition switch is ON.
