If it is dipping down to 9 and then coming up to 14 you either have something loading the system or your alternator is not putting enough current/voltage at idle. Put a voltmeter across the battery terminals or put a current clamp on the battery lead to see if this is true. What you are calling the Amp gauge is a voltage gauge.

Check to see that the battery contacts are very clean, tight etc and that you have not stripped the bolt hole if you used the side posts. Start with the basics first.
