Putting head on slant six

Finally did it! She’s purring right along!! Took it for its first test drive ( about 10 mile trip). Parked it, went to turn it back on to move it a few feet and it fired up then died. Now I have no power.

multimeter is telling me I have 12.5v at battery, and at starter. Key in run position I have 0v in my ignition switch, 0v at ballast resistor.

Here is what’s new
Battery,Starter, starter relay, coil, distributor cap and rotor, NSS.

thoughts?
