    The 12.3 is with nothing on just battery by itself. The battery is prob 5 yrs old and alternator is fairly new. We live in hot weather (Tracy, CA) but not as hot as Bakersfield I will replace battery and see how the voltmeter on dash does Thanks War

    So I put a multimeter on the battery it read 12.3 when I started car it went to 14.4 and when I turned on lights and heater it went to 14.7 so now I'm assuming it's the gauge cluster. Does that make sense or should I check something else ??

    Yes the dash gauge. Should I put a voltmeter on the alternator?

    i have a 05 GMC Yukon Denali My Voltmeter runs between 9-10 but when I turn my headlights on it goes to 14 and stays there. I did replace the alternator with one from Napa and it did the same thing. Any thoughts
