Where is the alternator fuse located on a 1988 Chevy Celebrity?

There isn't a fuse specifically for the alternator on a 1988 Chevy Celebrity (or most vehicles). The alternator's output is regulated internally and is directly connected to the battery. Problems with the alternator typically don't involve a blown fuse, but rather issues with the alternator itself (like a bad diode, regulator, or brushes) or the wiring to the alternator.

If you're having charging problems, check the alternator's output voltage at the battery with a voltmeter while the engine is running. Low voltage indicates a problem with the alternator. Look for blown fuses related to the ignition system, however, as a faulty ignition system might indirectly affect charging performance. These fuses are usually found in the under-hood fuse box and the interior fuse panel. Consult your owner's manual for the fuse box diagrams to locate these.
