>So . . . for all you electrical wizzes out there . . . . is that normal?
If
you short the two wires going to the ignition warning light bulb . . .
should you still be able to turn off the engine?

Nope. The ignition light indicates a voltage difference between the white
wire and the regulator power supplin in the alternator. If the bulb is
bypassed the alternator is generating voltage which is being fed directly
to the white wire which powers the coil (and everything else that is
supposed to shut off with the key).
Next time this happens you can pull the white wire from the coil rather
than the high tension lead.
Another thing you could do is put the transmission in fourth gear and dump
the clutch with the other foot firmly on the brake. Once the alternator
has stopped turning it will no longer be feeding power to the white
circuit.
Or you could manually operate the anti-run-on valve. (Oh, um never mind)
Cheers
