I am more concerned about the 11.6 than the 14.5. You should see 13.6 at the battery with the engine running and the headlights on. 14.5 for an extended length of time will be a little hot for the car battery. My guess is a corroded connection, resistive fuse, or too small a DC power cable.
Another assumption. Lets say the car battery is actually 13.6 and you meter may be reading high. Then under load you will still have around a 3 volt drop. Just a guess, and your meter may be just fine. I have seen power taps onto the battery cable become resistive and some folks even put an eye connector under the bolt connecting the cable to the battery - will work for a while.
