There is a 175 amp large fuse between the alternator and the battery.
There is a small inline fuse between the alternator and the large fuse.
The big fuse on the fire wall is major protection.
The small 20 amp fuse powers the altenator regulator circuit.
One of them might be blown.
To see this circuit, look in the Haynes manuel, page 12-17 at bottom of the page.
Be sure the plugup is in place and no pins are bent over.
Good luck.
