Is the voltage gauge accurate?
I was wondering if the voltage gauge in the instrument panel is accurate? Mine usually starts just a little above half way but if I turn my lights on and/or plug my ipod in cigarette lighter and turn the stereo on, it dips below halfway but not into the red. If I turn the stereo off and unplug the ipod, it doesn't go back up. By the time I get home (35 minute drive) it's a little lower but still not in the red. Should I be concered? I put an optima redtop on 1 year ago.

checked it, 12.3 off after sitting for a few hours, 13.4 running when my in car gauge says below half after driving 30 minutes. I thought it was supposed to be 14v engine running?

FYI I got new thicker battery cables from innovative wiring and I get 14.3 volts when running now, and it feels more powerful too. It's a very finicky car though, it had already been running good, the new cables just made seem even more powerful, it maybe in my head, but the voltage increase is real.

my gauge will start in the middle, then work it's way down to the red.
battery was just replaced and still the same thing. voltage while running is 14 volts at start up, then drops to 13.3-13.6 after running, yet gauge is in the red. i've just given up on it.
edit: also changed the 12 gauge stock alternator wire to a 6 or 8 gauge, can't remember, and added two more grounds, didn't affect anything
