Please report back. Oh break out the wiring diagram, here is one, http://www.fordgarage.com/pages/awiringdiagram.htm
Ummm, no, the coil does not get power from the switch. Go study that wiring diagram again. The coil gets POWER from the terminal box, all the time, via the black wire. The switch provides a GROUND to the coil, with the red wire and through the points, when it's turned on and working properly.

So if the switch is defective and providing a ground, or if the red wire from coil to switch is shorted to ground, the coil has current running through it and will get hot.
