OK, so now I'm really confused.

I pulled the + wire off the coil - with the switch to "run" I had 12+ volts. So I figured the ignition switch is OK and with the other symptoms, I swapped out the coil.

Now I turn the key and I get I very short burst of power and then nothing. And now the + wire to the coil shows extremely low voltage with the key in "run".

Bad ignition switch after all? Or something else?
