Ever since I got my new alternator from Ford, I will get the very occasional battery light; stays on maybe one to two minutes, maybe once every other week. It really hasn't been that frequent.
Well, the other day when it came on, I checked my UltraGauge for codes and noticed the voltage was at 15.7 volts. The light disappeared when it dropped back below that, bounced a couple times back and forth popping the light on and off, then dropped back into the 13.6-14.4 range. My thought is the light is coming on telling me the system is over-charging.
I'm not really sure how concerned I should be with this problem or if there is anything I really can do to fix it. The few random times I have seen it, it hasn't stayed on for longer than a couple minutes and then I won't see it again for days or weeks at a time. The alternator was supposed to be new and the battery is only a year old as I replaced it last year.
