As long as it isn't sagging below that then you are probably OK, but the alternator and regulator should be able to maintain a steady 14.1 at idle.

It's definitely not maintaining any kind of steady voltage, at idle or while moving and regardless of the absence or presence of a load.

I guess I'll just swap the alternator and see what things look like with the "new" one.
