What would cause an alternator fuse to blow?
If it was the fusable link, it is possible that some of the diodes shorted to ground. A third possibility is a mechanic accidentally shorted one of the alternator terminals to ground. The last possibility is the wire from the fuse to the regulator or field terminal shorted to the body of the car.
Where is the fuse for the alternator is located?
Sometimes, they are located on the inside of the fuse box cover. Replace the alternator fuse by pushing the new one into place using your fingers.
