Problems after alternator replacement

58 reads but no replies, so will see if I can get things started. With the PCM relay fuse blown a lot of things don't wake up & function, so you need to trouble shoot why this fuse is blowing???
Was it blowing Before the alternator replacement & if not When now in the start cycle is it blowing???.
Did you have the replacement alternator Bench tested before leaving the store with it??? Its usually a good idea for us to bench test All electricals before leaving the store because new / reman / rebuilt / salvaged, doesn't automatically make em good!!!
If it doesn't blow @ KOEO, before cranking the engine, use, borrow, or come by a ELM scan tool & running FORScan diagnostic freeware on the viewing device of choice, as discussed here & have it scan for trouble codes. Low Cost ELM Scantool - Ford Truck Enthusiasts Forums (ford-trucks.com), as this inexpensive but powerful combo can query All of the vehicle computer / controllers for trouble code clues, including set, pending & Ford enhanced codes, then post All code Numbers as they can help focus a trouble shoot.
Some beginning thoughts for consideration, let us know what you find.
