On the "T" plug that goes into the back of the alternator, the vertical part of the T should be showing 12 volts while the ignition is on. This sends the signal to the alternator, letting it know the current voltage of the system so it knows when to start charging. If you don't have 12 volts showing at that part of the plug, then the alt will not enter charge mode.

If it shows no voltage, then check the fuses under the dash.
