George

Start up the car, keep the alternator hooked up, using a test light or 
volt gauge, quickly unplug the large brown wire from the back of the 
alt, hit the terminal with the light or gauge lead, if the light lights, 
it's working. If the gauge reads 13-15 volts, it's fine.
Some (Lucas for sure) alternators will burn out a diode if you run them 
with the battery disconnected (or the main lead to the battery from the 
alt) So do it quick.

You can do the same test by removing the hot lead off the battery and 
checking it to see if it has volts.
