charging system voltage.
My truck is a 2012 Silverado 2500hd 6.0 liter gas with 40,000 miles that I've owned since new. A couple months ago I notice that the voltage gauge was running quite a bit above the 14 volt point in t...

Actually the site says 14.8-15.0, which is pretty close to what the OP measured at 15.1. Charging voltages over 14.5 are OK if the ambient temps warrant such, and since the OP lives in Michigan and it's March, it is certainly possible. I wouldn't expect to see over 14.5 at all in your neck of the woods.
Modern voltage regulators are 100% solid state and like anything else electronic they tend to be binary: either it's working correctly or not at all. Regulators will fail either full off, where no battery charging is taking place, or full on where the voltage is completely unregulated and cooks the battery in short order.
