I don't know if you still need help but i just did mine. 99' ranger xlt
First i unhooked the wires in the back of the alternator. A big connector and a smaller one. For me the hose from the air filter was in the way so i just disconnected one side and tied it back with some rope to the hood. Then I took out the three large bolts holding the alternator in place and moved the alternator in a little bit relieving the tension on the pulleys. Simply slid off the belt. Removing the alternator should literally take 10 or 15 minutes.
Also there is a diagram when you open the hood up of the pullys. It labels them, the one near the middle is the tension pully.
