There is a mega fuse in line between the alternator and the battery. If this wire was shorted to ground, you have most certainly blown that fuse. With a little luck, the fuse went before the alternator or voltage regulator was damaged.
If you do a search you should find the info about the fuse. Someone even posted a part number. It is available seperately even though the Ford catalog shows that you must buy the entire wire.
If you can get a voltmeter or test light down to the B+ terminal (the biggest wire) on the alternator you should have battery voltage. If you have no voltage there is a problem with the wiring between the battery and the alternator, probably a blown fuse. It is a very big fuse. Remember that you have a 130 amp alternator.
