ALTERNATOR BLOWS FUSE

1990 Jeep YJ

Electrical problem
1990 Jeep YJ 4 cyl Four Wheel Drive Manual 140000 miles

1990 Jeep has 30 amp fuse in fusible link. Alternator charges fine at low rpm. If you rev engine it blows the 30 amp fuse and then will not charge at all but everything else works fine. Auto store tested alternator. Says it is fine.?
