1.check for TIGHT conections at alternator, and Alt wire(BIG WHITE wire) at fuse box under hood. Make sure none tried to rewire an obd1 alt. into the car.
2. Also, ANY funny wires under hood.......follow them, see where they go. Make sure no one tried to wire their ricer lights into the harness.
3. unplug the speed sensor and drive it for a day. see if the fuse blows like that.

LMK.....
