Use a voltmeter red probe to alternator B+ connector and black probe to a ground .. you should be getting 13 + volts with engine running @ idle if oyur not alternator is bad still ... have you checked the fusible link in cable from alternator to battery !

Yes, I have checked fusible link, it's good. I am beginning to think that the "Exciter" wire which supplies 12v to the alt. Is not doing it's job. If you can help me fix this problem, I will make a donation to the board, however, I believe in payment after service has been successfully rendered ! Thank's, Steve.

Thank's All for the feedback ! I took the truck to a local shop yesterday, and after much Head Scratching & Foot Shuffling, it was determined that the underhood fuse block was incorrectly labeled ! The slot that was labeled as being the 15 amp ALT. Field slot, was not. The slot directly across from it turned out to be where the 15 amp fuse needed to be installed to energize the ALT. FLD with the voltage needed to cause the altenator to charge ! She's charging like a champ now ! Once Again, Many Thank's, Steve.

Could you explain which fuse is wrong for future aid to other people? Is my diagram of the fuse box wrong?
