The Alternator is not charging your battery , you have a pinch wire most likely or faullty connection at battery or Alternator

The alternator may be putting out the voltage but how about amps? Check your ground connections as well. Since you replaced the engine make sure all the ground straps/wires are hooked up. You really don't want to test the alternator by disconnecting the positive (+) battery cable. That's an old old old time charging system test which can create a power surge that will fry the electronics in a more modern car. HTH. - Jim
