      Yesterday I was driving, and the "Check Charging System " message popped up on my message center and also a light came on. It went away seconds later, but then came back two more times but they went away after a few seconds. This used to pop up often, and when my car was getting another problem fixed at the Ford Dealership they replaced my alternator (few months ago).

      Today when I was driving a heard the beep (the beep that goess off when there is a message or low fuel level), but no lights came lit up on the dashboard and no message came up. I heard this beep a few times...

      Any ideas what the beep is or why it said Check charging system?

      My first guess would be a failing battery, second would be corrosion build-up, and third would be worn cables (since you had the alternator recently replaced, it doesn't make the list). Check your battery's voltage when off, cranking, and running. Then inspect it for cracks, leaks, bulges, or fluid level (if it is serviceable). Along with that, check the terminals for corrosion buildup, as well as the ends of the cables going to/from the battery, alternator, and engine block. Then also check ground cables for corrosion, as well as verifying there are no split, cracked, fractured, or cut cables in any of the above. That should give you a good baseline to start with. Good luck.

      Battery Voltage with multimeter = CHECK
      Cables were replaced 2-3 weeks ago = CHECK
      Corrosion = Check
      Tightness = Check
      all the wiring = Check


      Maybe a belt problem? I'm not too good with engines so I don't know how to check the belt. I heard that might be the problem...

      Have you scanned your Explorer for diagnostic trouble codes?

      check the connectors going into the back of the alt...sometimes they get corroded inside.

      check to make sure your batter cables are tight. Last time I had work done at a dealership on my Fusion they didn't tighten the cable and I kept getting the message when I would hit a bump.

      not sure if this is relevant or not but , i heard that same beep twice and it was driving me crazy, i found out my back hatch wasn't closed securely and every time i went over a bump it would beep but wouldn't say door ajar it was weird..also when i was low on brake fluid when i would floor it or go over a bump i would hear the same beep but no message displayed. i refilled brake fluid and it went away. Both situations it was the same beep as stated in first post. sorry if this is off topic.

      Update.. 2005 Explorer V8 XLT Battery light on and The "CHECK CHARGING SYSTEM" on the message center was on after using a refurb from Auto Zone
      ....
      AutoZone alt. was returned,, I was getting a full charge, but i don't think it was talking back to the truck to turn the the battery light off in the truck even though everything else was working, meaning 14volts and charging.. got a full refund..
      took that money to the Ford dealer and got one from them..
      Part # F8OZ-10V346-CARM This one had a 3 terminal connection I believe the AZ one only had a 2 terminal connection, even though the cable from the truck had only two wires the green and orange one.. The middle connection was not being used i guess.. any way all is well..

      Got 14 Volts on the B+
      Got 14 Volts on the Batt terminals
      The "CHECK CHARGING SYSTEM" on the message center is off
      The Battery Light is off as well..
