sir , the altenator has 3 wires at the connector correct ? a white/red , a green/white and a black , the white/red wire is involved with a 10 amp fuse to do with the charging meter / gauge , the fuse located behind left side of dash .. the green/white wire is is involved with 2 fuses , a 10 amp ECU fuse and a 25 amp Main fuse located at left rear of engine compartment main box , and the black wire is involved with a main 80 amp fuse at the main box also . both of these 2 wires end up at the positive side of the battery , please verify all these fuses are good . if they are indeed good , then open wiring would be next step verify continuity on black and the white/green wires . i would post a link to diagram but autozone repair info site is down at this time . if ya need more help , please ask .

check the alternator fuse that can be a fuse link by the battery pole,check alternator voltage on the alternator red wire or connector,it should the same as on the battery ,check ground wires for loose intermitent contact

turn your vehicle on, disconnect the battery, both terminals(while truck is still on) if it dies on you, then either the alternator is bad or wiring is wrong. if it stays on, then you may have a bad battery or voltage regulator. Check the voltage on the battery before you turn it on(should be from 11.5v-12v), when you turn it on if the alternator if working properly you should have around 13v-14v.
