I have a 2006 explorer and I had my check charging system light go on and

Ok so I have a 07 that's been doing this now ur all going to be happy I have found out what is going on the ground wire connector from the alternator was bad it had came off just enough to send that code now that I changed it it's been over 7 months n still not came back on a 25$ fix if it wasn't for advance auto parts guy checking my battery and alternator would never have figured it out bc he started to push on that wire while I was in the cab so hope your guys is just the same

I have a 2007 as well, V8 4.6l. I replaced the battery and the alternator recently and that check charging system still comes on. I’m going to have to do a little more digging. I wish it was as simple as a ground. I will be checking that as well in the next couple days. Thanks for the heads up.

The battery is brand new got it 2 weeks ago. The dashboard lights that I get is the battery, oil and check charging systems on it. When I put the key in and before I start the car I always get all the lights lite including the battery light. The one thing that puzzles is that when it shuts down I pull over and then it starts up again and I am able to go where I need too. We are taking it to the dealer tomorrow but my problem is that I don't trust them and they charge so much for the work to be done. This car in the last 2 months has costed me $1,000. This is my 3rd Explorer and it is the only one I have had this much problems with.

Had a customer come in complaining with the same symptoms on a 2007 Ford Explorer XLT 4.0L. After a bit of troubleshooting found the Harmonic Balancer center rubber damper is coming apart and allowing the voltage to have slow drops when it was slipping. Even affected the power steering when it was first started until the balancer heated up from slipping. Check the Harmonic Balancer closely and watch the rotations of all the pulleys while it running. Should be able to see the belt rotation slow down and sometimes just about stop.
