Thanks Sid....I found out it was the new alternater that was just installed.  I returned it and got another one.....and...WHAL-LA!!!!  now its the perfect volts.....13.4 to 13.8

  Mitch, my suggestion is to first check the voltage (engine running of 
  course) with a digital voltmeter. I would make the measurement at (or as 
  close as practical) to the battery.
