That's completely normal. The reason it's not putting out the higher voltage is because the computer is telling it not to, since it thinks it doesn't need it. I have a 2011 and it's the exact same as your 2010 pretty much, and I sit at around 13.8V even with my 270A alternator I have in. It's no big problem to not be sitting at the 14.4V mark, because even with a high powered system, that isn't really losing that much power output from your alternator.Where are our cars most happy 13.9? My cars sitting at anywhere from 13.3 13.4 13.5 13.6 with the system off or on 1/0 gauge to 4 gauge and a spare battery in the trunk...
I'm not sure what you mean by a happy knob, unless you are refering to the thing that sort of acts as your PCM...and i have no clue about that.how do you put in a happy knob also how hard was it to swap out your alternator? from the bottom right? and have you done the big 3 yet where did you run your grounds too on the subframe? I need a place that's out of the way of moving parts.
I kept the stock in place to the fuse box, but ran my 0 gauge wire straight to the battery.yes I know and I will and yes I know about the black plastic cooling shroud so I would be running the positive from the back of the alternator to the battery not to the fuse box correct? I know that on the newer style silverado's you run it to the red fuse box by the battery.
Yeah they keep your alternator running at the higher voltage for the purpose of your amps and stuff...let me know if you find one for the 2008-2011 focus and how muchok because the MLA looks pretty bad ass and from what I've seen on the youtube video wow they see a huge voltage jump
