Hello and welcome to JustAnswer! I apologize for the extended wait time you experienced, I've only just come online now and would like to assist you with your question.

There are a handful of things that could be going on and it's going to require some testing to determine exactly what is wrong. Disconnecting a battery cable with the engine running can instantly damage electrical components because battery voltage can spike extremely high if it's actually charging, so you'll want to discontinue that.

The alternator is internally regulated so you either have a wiring issue, possibly a blown fuse, or it's possible that you got a bad replacement. Are you hoping to do the required electrical testing yourself?
