If you have the alternator wired as the diagram shows, did you verify you are getting 14V+ on your exciter wire from the truck? If you aren't, something is wrong in your wiring. If it is and the alternator shows no output, something is wrong with the alternator. So first verify supply voltage to I terminal, then verify voltage output.
