Hi @Williamnelson can you tell us a bit more about your vehicle and the history of this problem? People might be better able to help with some more info.

You have a broken wire somewhere.  
Check for battery voltage at the stud on the alternator.  
Next, there should be ignition voltage, 12+ volts on the blue field wire on the alternator when running.  
Measure the voltage of the green flied wire on the alternator, it should be between 0 and 11 volts depending on charging system demand.

My first guess is the fusible link.
