Have the alt checked while on the truck, output voltage at the battery post should be 13.5 to 14 @ idle with lights & heater on!

With the vehicle turned off, Touch the voltmeter to black on battery and the red to the connection at the alternator. If the read is 0 then you have a break between the alternator and battery. Follow the red wire from alternator to the fuse box. Is it possible the fusible link has burnt out at the fuse box.
