Electrically disconnect the alternator and reconnect the battery. If fuse 14 still blows, the generator circuit harness is shorted; if it does not, the alternator is internally shorted. The later computer replacement and reset questions were not answered.
After installing a rebuilt 4.0 SOHC engine in a 1998 Ford Explorer Sport, the owner reported that underhood power distribution box fuse 14, identified as the generator/voltage regulator fuse, blew whenever the battery was connected. The expert advised disconnecting the alternator electrically: a fuse that still blows points to a shorted harness, while a fuse that holds points to a shorted alternator. The owner later said wiring work did not fix it, then reported the engine would turn over and asked about replacing or resetting the computer, but those questions received no expert reply.
