Usually a fusable link
You failed to mention what year the S10 is but, most of them use a fusible link to protect the alternator circuit.
The license plate light circuit is protected with the tail light circuit fuse.
Clearly there is something wrong with the car besides a bad alternator fuse. Without more information I cannot hazard a guess. But you may want to check the charging system overall to see that it is working correctly. That will include the battery and alternator.
You can find your 1999 Ford Expedition front windshield wiper fuse in the fuse box. The windshield wiper fuse will be in the second column, fourth from the top.
Any time a fuse link burns out one should suspect a LARGE short condition in the harness. Shut off all accessories and pull all fuses from the fuse panel. Take NOTES or replacement will be a pain. Disconnect battery if connected, Use a DVM and check the resistance of each accessory at the fuse side to ground. A low or zero ohm condition indicates trouble in that circuit. Also check from the alternator B+ to the alternator body. A low reading here would make one suspect the alternator has an internal short. Also check for a failed/shorted starter cable or starter.
The wires that go off the alternator are fused, meaning that will break the circuit by melting.
Alternators are not in a fused circuit. If your alternator isn't working, it's because either the belt is broken, there is a shorted circuit somewhere, or the alternator is faulty.
