Not getting 12 volts to coil

I'm waiting for a cleaning chemical to arrive, and reading your wiring basics, 1968 article. All your ignition switch tests worked. What a relief. Thank you. I should have figured them out myself. All I want is 1 volt more at the +coil. After the bulkhead male/female cleaning, if it does not work, I'll follow your plan for voltage drops in the engine bay. I have an original 1970 alternator, which a took to a starter shop and they said was good. New starter, coil, dual points, rotor, ballast resistor, plugs.
