I started it again and this time it was reading 14 again..The batery terminals are clean and tight and the car runs well....Any Ideas? Thanks in advance of any replies

I would look at the back of alternator and make sure all connections there are clean and secure and measure at this point with meter for voltage of 14.25 with engine running.....if your alternator has a connector with small wire remove and inspect as these tend to get corroded...
