alternator voltage output
From:

      My question is this, what is the normal output of the alternator in voltage?  My
      volt meter is reading up to 14.7 volts when running around 3000rpm.  Is this
      normal or should it max out around 13.7?
      
      If this is high, I guess I need a new regulator?  My problem is the Garmin system
      seems to fluctuate as the voltage gets up to 14.5 or more volts.  When you
      pull back the throttle and let the voltage drop, things settle down.
      
      Thanks,
      Curt

          13.8 is the MINIMUM needed to fully
          charge a lead-acid battery . . . but it
          takes a LONG time to top off. Starting
          batteries in vehicles are generally recharged
          at 14.2 plus/minus 0.2 and 14.7 is not
          too high.

          Is this a piece of aircraft hardware?
          The voltage level you cite should be
          no problem. What system are we talking
          about?
