Yea, same as mine was doing! When you top out the windows it will dim a tad but it shouldn't be much. Check the battery voltage when the truck is running with all of your accessories turned on and see how far the voltage drops. Mine dropped to just above 12v at idle and it would idle up after drinving around abit with everything turned on.

Yea, I don't think that's normal.

12.25 + with engine off.

Over 13 running.

That's for a healthy battery and charging system. I don't think I'm wrong here ? Well, that's what I get. I'm still running the original alternator, you believe that ? lol - It is lol.
