From what I understand a consistent 14.5 volts is high for a stabilized voltage for a vehicle having a charging system controlled by the ECM. The old standards of when the alternator was controlled solely by the voltage regulator and returned consistent readings within a very narrow window no longer apply.nothing wrong with 14.5. check for a/c voltage
Regardless, I don't know what voltage I have, which is part of the problem. I am reading anywhere from 13.0 VDC all the way to 15.15 VDC depending on when I check it and what meter I use. I first need to know which meter reading is correct before I can begin to figure out if the reading is good or not.
