Where is the fusible link on a 1995 buick regal 3.8 located?

Most modern-day cars don't have fusible links (lumps) in the wires, as in days of yore. Instead, they are often the larger fuses in the under hood fuse/relay box. Test them just like you would any other fuse:

There may also be a "mega fuse" on the end of the under hood fuse box, where the wire from the alternator joins the box.
