My normal operating voltage has been about 14.8 volts. After I installed a new battery I am climbing to 16 volts+. I removed alternator and took to shop--they tested and said all was fine. I re-installed and had same problem. Then I installed a new voltage in alternator--same problem. A volt/ohm meter has confirmed goos connections including ground between battery and alternator. Could a battery cause high voltage fluctuations?
