That's what I'm thinking. A cold alternator/engine with a cold battery will normally boost the output voltage a bit, like the high 14's and drop off after things warm up. 16V is way too high and will cook the battery eventually. As 'Wire2 says, double-check the onboard voltmeter and suspect the regulator.
