The ignition wire is disconnected from the ballast resistor.
Key off should be equal to all the wires at the key switch being disconnected.

That does leave a possible connection to ground. The voltage regulator still has a ground connection (mechanical) and possibly through the rotor too in parallel.
Disconnect the power into the regualtor (blue wire) and a digital ohmeter should MegaOhms or the same symbol it shows when the probes are touching nothing.
