You either have a shorted starter solenoid that continues to send power to the starter, a bad starter, or there is a problem with the ignition where a short is causing it to keep cranking. I would recommend beginning with the solenoid connection, make sure no wires are touching where they shouldn't and then disconnecting it and seeing if your problem goes away. If it keeps cranking, you know your problem is from the solenoid to the starter, if not then it is before that point.

You don't really need to check for continuity from those places to ground, as that pretty much means nothing. You want to check for power on the wires that should not be powered up except during cranking. Then you will find the problem easier.

I do not have access to any Ford diagrams, since I'm a GM technician, but good luck to you. One more thing, just because you have a 'new' rebuilt starter does not mean it can't be faulty already, so be sure to check everything thoroughly.
