Check the large probably 100 amp fuse under the PDC cover. Is this a 12 valve or 24 valve engine? If it's a 12 valve, it may be a bad crank sensor. It tells the PCM to turn on the ASD relay which supplies power to the alternator field.

What Voltage do you have at same Place with Engine Running ??
Now At wires Were they plug into Alt ,Top. Wires in White Plastic Clip, Do You Have Powe With Key On ?? How Much Voltage??
Jump across the 2 in the clip (with Engine Running)ONLY TEMPORARY!! Do You Have Voltage at Battery ?? How Much??
If Over 13volts With Clip On (Jumped) You Need A Internal Voltage Regulator ..

do a continuity test from the large red wire on your alt to the battery,could be a fusible link or broken wire,sometimes a wire will break within the sheathing so it won't be visible by eye,check all conections for corrosion and either clean or repair

I had the same problem on a 94 dodge with the cummins. It seems the crank sensor that reads from a notch on the harmonic balancer was the problem Without this sensor reading that the engine is running the alternator wont charge. Possibly the same problem with yours

Check the main power fuse that goes to the alternator output. if the alternator went out it could have burnt this fuse also.
