Where is the fuse to alternator on a 98 Trans Am?

The 1998 Trans Am doesn't have a fuse specifically for the alternator. The alternator is regulated differently; it doesn't use a fuse in the traditional sense. Problems with the alternator usually involve the alternator itself, the wiring to the alternator (which might have a fusible link), or the voltage regulator within the alternator.

If you're having alternator issues (e.g., charging problems), you should:

* Check the alternator's output voltage: This requires a multimeter.

* Inspect the wiring harness: Look for any damaged or corroded wires leading to and from the alternator.

* Have the alternator tested: A professional auto parts store can test your alternator to see if it's functioning correctly.

While there isn't a specific "alternator fuse," there might be a fusible link in the main power wire supplying the alternator. This would be located somewhere in the main wiring harness, possibly near the battery or the alternator itself and is usually not a replaceable fuse, but a part of the main wire itself. You'll want a wiring diagram to identify it if you suspect this is the issue. A qualified mechanic will be best equipped to identify and address this type of problem.
