Rebuilt alternators don't always work,  have it checked.  But first, there is a small "excite" wire that goes into the alternator, if this wire does not provide some voltage, the alternator will not put out.  Look for this wire and see if it has voltage when truck ignition switch is on.  There can only be 2 or 3 little (12 gaugeish) wires to the back of the alternator ... one of them should be carrying 12 volts.\015\012

Check for blown fuses& make sure the red wire to alt. is getting 12volts. also ford uses fusible links witch look like regular wires. usually you can tell by feeling the wire itself if it feels squishy and when you pull on it it stretches chances are its bad. try an ohm meter at each end no continuity no connection
