Disconnect the wire from the distributor to ignition coil terminal. With key on, the terminal with yellow wire from ign switch should measure 6v to ground. With nothing connected on the terminal going to dist it should also read 6v. If those are correct, ign switch, wiring and coil are all OK. If not 6v on terminal from ign switch, then wire or ign switch.

Keep the meter on the coil terminal going to distributor and touch or hold the wire going to distributor to the terminal. If the points are open you will still read 6v. If points are closed or if there is a short it will drop down to 0v or the .25v slightly above 0. If turning the engine slightly to make sure the points are open does not cause it to go to 6v there is a problem or a short in the distributor.
