changed alternator...wont crank!

The reason I changed it is because the pulley fell off lastnight and I had an old alternator that I dont know if it works or not and put that one on. I charged the battery and even tried another battery that I know is good and still nothing. Both alternators are stock ones and dont have any powder coating on them. I didnt try to start it today before I changed the alternator today, wish I would have just so I knew if it would have cranked or not. It had been on the battery charger all night because the battery ran down after the pulley fell off last night, I dont know if that is a worthy clue or not? Also it has a painless wiring harness in it that i didnt install so I cant make heads or tails of it as far as fuses go. I can get the engine to turn if I jumper the solonoid but not with the starter button (no key) just toggles and a button.
