    as long as your getting higher than 13 out of your alternator, you're fine. 12.6 i think is stock battery, anything higher is charging. very, very slightly since your battery is almost fully charged. at a near dead battery i think you will show over 14v

    Just what kind of voltage are you getting??

    The wire coming off the Alternator B terminal might be getting old and tired .

    Dirty Battery terminals .

    Poor grounds ??

    either way. 13.5 volts is normal. that's what my truck does all the time, unless I leave my lights and/or radio on for a while.

    Maybe too much resistance in the battery wires?

    I know you said the alternator is new but if you are only getting 12v from it, it is bad too.

    I read the first post to say he is expecting 13.5, not that he is measuring 13.5. In post 4 he is saying he is only getting 12. If true, the alt output is the problem.

    there are a few screws that hold the fuse into the box. I don't quite remember how we got it exactly... but we ended up breaking the fuse before we figured out it was screwed in LOL
