2012 Lincoln mkz
V6
I believe 3.5l?
Passed couple days can only start it with a jump. Took it to get a new battery and the current battery tested great. No problems found.
Doesn't turn over or crank at all. Power seats don't work. Radio don't work. Horn sounds like it want to blow but not enough power. So wtf could be causing it to not get any power through the battery?

2012 a bit new BUT I think the battery bolts are funky vs many from past years. States uses an Allen wrench to fasten?
Best guess is that it's not tight enough or can't make a good connection right at the battery. If this thing is under full warranty still you shouldn't be messing with it at all really,

battery is a part of the system- did you check charging system, a 2012* I would ask is the CEL on, did you ck for codes?
Is the vehicle STOCK- no added electrical ie remote starter? audio? lighting?
* as tom suggested - warranty?

The fact that this starts with a jump narrows it down to two possible things only..........
Battery discharged for whatever reason
Poor connections at the battery.

I tried to find the funky connection from EXACTLY a 2012 Ford product and they were AFUed before the second tank of gas from new - contractor's vehicle stuck in my driveway. Not here for me to touch at all just to wait for it to get towed out as it was sqeaky new.
Tow driver pointed out the cable was just loose and it was funky. Yes, it did twist with a finger and neither of us touched it. Owner mad as a hornet of course not present for the tow so off it went.
Maybe and can't know that the fricken things are shipped with batteries disconnected and set up by dealers. Just can't know diddle for a two year old vehicle for sure even with looking it up???? I think you need to tighten what I vaguely recall in sequence of an Allen head then another or the connection just wont be right????

OK so get this. Took it to auto zone just in case. They hooked it up and their machine instantly said dead battery. Rest wouldn't even go further with the battery being 100% dead. So vim crossing my fingers hoping that was the only problem and if that is the problem then the first crap place I went to needs to upgrade their equipment which read that the battery exceeds the average.
So another question. With the car being 2012 isn't that kinda new for the battery to die? Something draining it? Other then a car charger in I have nothing extra than standard that uses anything. Lights were set on auto but switched to manual just in case.
Nothing positive yet. We t tell for a few days if it keeps starting but a dead battery definitely makes sense. So fingers still crossed and damn that first machine.

Hey - Parts chains are handy but it's not their job to fix your car but rather sell parts.
If battery was tested uncharged first - no info on it's condition will be known. If tested by the outside of clamps that are NOT connected well to the actual battery as it can't so much as honk the horn then that's what it would show - no battery power.
It takes a jump (not recommended without knowing just what you are doing and with what) you are jumping the cables not the battery.
Why are you fooling with this? You are risking any potential warranty or recall of some possible expensive damage already that will not be honored by fooling with it.
Yes - a battery can be bad new, days, old, ruined in handling and destroyed by allowing one to go dead too much or overcharging. Most that last a month are good but exceptions to all.
Everything you've noted suggests this battery can't make a connection to the cables properly. I don't care if they look all perfect but it starts or did when jumped and battery for that moment wasn't involved at all,

Tom no offense but what the he'll are you talking about? Are you one of th hose grumpy I hate life type of people or what? Settle down there badass.
So you're saying changing a battery is going to mess up my car or void and warranty? Not sure what you are saying about it being tested the first time when it was dead. The first machine they hooked it up to didn't say it was a dead battery. The first machine said the battery was 100% perfect. The 2nd machine at auto zone said it was dead and needed replaced before they could test the alt. Or anything else.
From my understanding it wasn't the fact that the battery was not making a connection. It was the fact that the 2nd machine said the battery was dead and needed replaced.
Not sure I'm understanding anything you said

Relax sport - here to help you with what should be so dumb easy to figure out.
You have stated the car does about nothing electrical but will plain start with a jump. That says about it all right there.
See just any top post type cable.........
Top right anything of the sort is grabbing the post of the battery dead or not but might not make a connection. The outside of that if jumped with enough power would send the power on to the car without much regard to the battery at all and does start as you said!
If battery was a total dead short by itself the jump would suck into the dead battery and near certainly wouldn't start or power the car with anything. There would likely be a reaction notices just with the last connection to jump it as well.
This is primal so far. It's near sure that somehow it doesn't connect much but some. With that it can jump but such a weak connection it can't even recharge and surprised the thing runs well at all if weak enough. All this without complications of any antitheft, remote starter things or whatevers.
Note that starter motor is the huge draw required. The rest of electrical things all thru don't need what the starter requires in AMPS to operate.
Note that because you can't say or know how this was tested or charged if it was by the outer ring of those clamps with battery in place you get the same fault it has - no connection to test or charge worth a dang.
I can't be sure of anything not right in front of me and sorry if I missed a detail putting this off on the wrong tangent. What I'm thinking is you get this running by jumping and any lighting or powered stuff is struggling with power from the alternator and maintain a so far unknown battery at full charge all the time it's risking electrical things throughout.
Seriously, this seems like just a fluke right at the battery that is going on even if it looks right it smacks that the issue at least started right there, that's all. If you can't prove that's good and can with even cheap testing the rest is wasting time and harming things,
Peace friend. I do this endlessly for free many times to save people from themselves,
Tom
