.Ford Taurus Charging System

iam having the same problem with a 2005 taurus ,may b a fuse or a dead ground somewhere.

I am having the same problem with my 2006 Taurus.

I am having the same problem with my 2008 Ford Taurus. The Check Charging System still comes on I was told at O'Reillys it was my battery. And the Check Charging System still appears.

I have a 2006 . Check charging system light goes on and off at random. Changed alternative and starter and battery is also good. Very frustrating!

Ford builds crap and charges a premium to fix crap.The systems are overly complicated and needs a much simplier design

My altanator is working, new battery, new battery post, wire connections are good and yet the charging system warning still comes on.What a piece of crap!The Russians build simpler , better cars!

Guess its all ford taurus. I have 2005.. Just bought my car feb 13 this year and my check charging system keeps popping up every few days... I looked at battery which is only year old.. Everyone says no issues... But pops up...

Ok so I'm dealing with a similar problem with my 2007 Taurus SEL At 66,500 miles currently (bought used from a local dealer at 64,245 mi ). Replaced battery as standing voltage was 11.3 v average after 12 hour rest. New battery standing voltage 12.4 v. Cleaned terminals, checked fuses, Measured charge rate ( new battery 14.3 volts, old battery 13.8 volts). Auto Zone load tester said, the alternator was bad ? So maybe; but what I have found so far is a bad connection between the alternator and the sensor wire plug (3 wire plug) on top of the alt. When I push on this connection all of a sudden the charging system comes to life and starts working again. Haven't figured out yet if it's a poor plug connection or a internal alternator problem. However I have not yet scanned for latent stored computer codes nor deleted those that can cause a reoccurring system error. Much like any computer they should be scanned for accumulated bugs on a regular basis. These are good solid cars but, like all American cars they may need some fine tuning and with a little love they will last and, be a reliable friend.

I have a 2006 Ford Taurus no charge light and passenger air bag light come on drove car home 20 miles battery completely dead. I charged battery and removed alternator and took them to my local auto zone they both tested like new car has 226000 miles it has been a very dependable car

i get a message on my 2004 taurus that says something about check breaks and then the car dies out... anyone have any idea?

I have a 2005 Taurus and have the same issue as the last poster (Zack)... Car died out today with the same symptoms... And news on what it was or how to resolve it ? Lights and all eletrcic was diying down as that wwas happening.

Having this problem ,2007 Taurus , recently bought . Replaced Alternator , light immediately returned .Mechanics checked ...all charging working perfectly . Sounds like I've inherited a nightmare flaw that Ford won't address. We should start a relentless social media campaign against Ford to address this problem.

My check engine light stays on my husband does something to the battery it goes off for a few hours to 2 days then come back on just now it says check charging system is that the same as check engine????? I have a new battery i was honna change the alternator but after reading these comments i see that wont help smh

Same problem on 2007 ford taurus, just had water pump changed and the entire pully system and belt...gonna change battery, hope it's not alternator

Reading the above posts, sounds like totally different problems. Some are one thing, some are another. I agree with the post that they have made them entirely too complicated. I have a 72 Chevy PU and have had NO problems. So, now on to my comments here. We have six Tauri in our family, and my 06 is the newest. None of the cars have had the P0622 codes show up except for mine. It pops up along with a battery light and says that I have a CKT F fault.....so far, have NOT found it. I have traced and cleaned ALL grounds, All Alternator and battery connections and still have it doing the same thing. Usually when it is cool out (90s?) comes and goes...sometimes twice in a minute or so and sometimes stays on for 10 minutes. I am now at the PCM which is a royal PITA, as only the dealers can do anything with them and they want $100+ to do it. My battery and alternator is new now, and I am about to pin point the #3 wire on the Alt Connector. I have good voltage everywhere on my car. The #3 wire is the Org/Yel wire that for some reason changes to Org/Light Blue after the Battery Junction box fuse F1.26 (10A) and then goes back into the Max Fuse (175A). I am about to pull out an old alternator from the shed that I had tested last year and it was good. Maybe stick it back in....but I also agree with some that MOST problems can be traced to a bad Ground. If I don't die of old age before I find the answer, I will post it here.

My son has a 2003 ford taurus. The battery light comes on and stays on and its been for week but the car drives fine and he just ignores it now. He drives to and fro to our home every week and that is about 70 miles one way. Not sure what to do because the battery is only a few months old and everything seems to work.

My ac clutch pulley locked up. By passed it with a smaller serpentine belt. Charging system still popping up. But my car had died. Now its working but the charging message still comes out

Have you checked your ac clutch pulley. It might have locked up like mine

You can by pass it with a smaller belt. Pulley size of that car is 85in by pass the ac clutch with a 81and you should be good. I did it t for my wife's car

Check to see if all pulleys are turning. Believe me it might be your ac clutch. Is your ac running

i have a 2007 ford taurus se , the check charging system light came on repeatedly after i replaced both my battery and alternator, i put my volt meter across my battery it would read 14.6 no alarms,but then the voltage would drop to 13.7 and and the alarm would return! I jiggeled there not no NOW!plastic connector on the alternator the volt went back to th14.6. I cleaned the plug and receptacle with an old tooth brush and isopropl alcohol, the lights a

ECM check it change it. Its all the same Kenneth. ECM

Same here. 2014 Ford Taurus. A great American car. Why Ford has this one problem? I don't know. The chargibg light keeps coming on, chirpping-- check charging system-- I've changed already 2 batteries and 2 alternators, changed 2 lights each side (twice). Fooled me once, fool me twice shame on me. I always liked the Ford Taurus, But I need this car to work. It costs. Its costly for the average person. If this is intentional, like badeball, maybe congress should start adking questions about safety. Think about it Ford. Give me a break.

Here is how to diagnose if it's not the alternator or the battery and your battery light still comes on. For me, I had to replace the Computer (ECM) for you it will be a break in this wire or the computer. they are about $200.00 online.

So what was the fix for this problem?

I, 100%, solved this same issue with my 2009 Ford Taurus by going through every fuse in the fuse panels. I found a fuse in the panel under the hood that was not fully seated in the slot. It was making contact and the accessory it fed worked most of the time, I never noticed it not working. However, the fuse arced when I touched it between the fuses tab and the slot it slides into. The constant arcing between the fuse and holder was drawing more current than normal operation causing the voltage of the battery to occasionally dip bellow optimum voltage creating the system warning light to come on. For good measure, I replaced the fuse with a new one and made sure it was securely seated in the holder.

Which fuse and did yours overcharge when this problem occurred and in the morning the battery would be dead

Check the battery in your key my brothers 2008 taurus just did the same thing and we changed the battery in his key and it fixed it
