One test I do is to get the car running and then pull the battery cable. If the car dies, the alternator is not working.
With the number of experts that are or will reply to this thread, I am sure you will fix this quickly.
Did you test the unit after the rebuild?

That is a risky test because pulling the battery out of the circuit can generate a voltage spike that can kill lights electronics etc. assuming it is charging.
A quick test for the alternator is to put a volt meter on the output terminal
with the engine running and the field disconnected, voltage should be 12.6 or so then jumper the field terminal briefly to 12v and watch the volt meter it should jump up if it does you have a wiring /regulator problem if it stays at 12v you have an alternator problem (warning do this quickly as it can overload the alternator).
