A short will blow a fuse or fusable link intermittently,but your description pionts more to bad contact at alternator circuit,loose or damaged wire or maybe voltage regulator at alt.,assuming drive belt is tight!

Disconnect alternator and replace blown power fuse and see if it is the actual alternator short or harness related. Always check your ground wire for corroision. Ground wires cause resistance problems and cause premature failures of electrical components.

How many miles do miles have to drive to reset my ford f150 computer


Hello,

Assuming the problems have been fixed it can take a few minutes to a few days depending on the drive time. The computer will eventually relearn everything. The PCM will adapt to your driving habits. It can take a while sometimes. Give it a week or so.
