You're ok with 14.7v. Now go back and open the EGR look around the pintle for carbon make sure it moves up and down. Also the manifold side-shine a lite in there. EGR don't cut it, we'll check idle speed stepper motor and Cold Start Valve or Injector, Perhaps maybe the Throttle Position Sensor for adjustment.
BTW about the Alty is this an Idle reading w/o a load comeback I'll be waiting just keep me informed is to what you have done and its results etc.
