    Hi - my battery gauge is showing the alternator over charging a bit. There is no fluctuation while driving, accelerating or deceleration - the gauge needle goes past the midpoint upon start up.

    What's the best way to throttle back the the charge so it hits where it's supposed to on the gauge?

    Take a meter and get a reading off battery, when running. Those idiot gauges are not accurate.

    That's about where mine sits all the time.

    That's about where mine sits as well.

    If you're worried about it, I'd take it to AZ or Advance and have them test it (it's free).

    Mine sits there as well. Wish my gas gauge wouldn't move from there

    It's not overcharging, that's where mine sits. I've measured voltage on it before, when I get back to where my meter is ill post up picks showing the difference. The computer will not overcharge the battery, but when you give it gas it's going spin faster thus producing more power, but the computer regulates current situation. I'm running a 160A alternator and the gauge is the same with it or stock.

    Did you get the 160 from a durango?
