    Alternator voltage?

    My charging voltage never drops below 14.5 and sometimes it get above 15. From what I understand it should drop down into the 12's but never does? Is this a feature that has to be activated by a dealer?

    Mine is the same way. I've only seen it drop to 12.6V when I bought a brand new battery and drove an 8 hour round trip. Only then did it drop briefly but it didn't stay there for long. From what I understand there are so many electronics that draw electricity, it will rarely stop charging/providing amps to the running electronics, mainly the daytime running lights.

    I believe this behavior is normal.
