need help/ not charging..I think

Hard to say if they did/ did not.

Next thing you can check, is identify the wire ---should be green--that goes from one field terminal to the regulator

Disconnect that from the alternator, and ground the exposed alternator terminal

Now see if it charges, and it should put out 'full output'. This will tell you if the alternator works, and if it does, it will tell you that you either have a bad regulator or a problem in the regulator wiring.
