I have an Alpine 143-BT head unit that has decided not to work. When I put power to it you can hear the eject mechanism inside making noise (CD eject mechanism). Nothing lights up on faceplate. How could you determine whether or not it is the faceplate or the actual head unit itself that is the problem?

It's called the K.I.S.S. preciniple ("Keep it simple, stupid!")... Takes the guesswork out of parallel/series wiring.
