I only have a service manual for a 2000 model, but it should be the same. Follow the smaller red 6 gauge positive battery wire to a dark green 10 gauge piece spliced in. That's the fuse link for the alternator. Tug on it. If it acts like a piece of wire, it's okay. If it acts like a rubber band, it's burned open.

A much easier method is to test for battery voltage at the alternator's output terminal. If you find 12 volts there, the fuse link is good. It's much more common to find worn brushes inside the alternator causing a no-charge condition. Measure the two voltages on the two smaller wires while the engine is running. The dark green / orange will have full battery voltage. The dark green wire should have less but not 0 volts. If you find 0 volts, the brushes must be replaced. You can often do that without removing the alternator from the engine.
