Maybe the voltage regulator went out on the alternator. Sending that light on for a MAX voltag. Just a long shot, because a stock alternator or even High output wont put out 14.5. Thats pretty damn high.. I HAVE a High output, and I MIGHT get that 14.5v. Especially if there is no voltage drop when you turn the AC and or lights on. just my .02 worth a shot, see if you can pull a code, stating too high a voltage or something of the sort.
