>>Key on run, red lead of volt meter to the + terminal on the coil, black lead of voltmeter to a ground. You should see somewhere above 6 volts or so<<

That would only be true if the engine stopped at a point when the distributor points happened to be closed.
Not much of a test. The test light will give better info, but what are you actually testing for?

Is this a NO START problem? What is the problem that you are trying to diagnose?

There is no electrical difference between a " (ceramic block with two posts) and a resistor wire". Both should have a resistance of 1.8 Ohms for a six cyl chevy distributor.
