Your post is a little confusing..... If the alternator passed off the car, why would you buy a new one?..... I'm not sure what you meant by "forced a fail"
Anyways....here we are........
A couple of quick things you can do is, 1st get test light and check all your fuses.... I believe that one just has one box under the dash but check under the hood to be sure......
Then with the test light check the large terminal on the back of the alternator where the large gauge wire bolts to, that should have 12v all the time.....
Depending on what you find would determine your next steps.........
