Umm try another dealer cause a check charging system shouldn't go off unless it does have a issue.

Welcome to this forum! Check your charging system voltage with a multimeter. Which year is your vehicle? You don't have anything listed in your profile.

Thanks for your help...but

it is a '05 explorer. dealer did voltage check twice over three month period and both times the alternator and battery checked perfect. 'some sensor problem' was the excuse. car starts and runs fine. it has a new battery.

i understand the voltage output issue but since the dealer checked it twice and everything is working then i just want to 'KILL THE DAMN BEEPING NOISE'.

i can live with the blinking dash warning. i called the dealer again...no suggestion. called ford customer service...twice...'see your dealer'. i want to put out a fuse that controls the noise but i can't figure out which one it is. yes i know it might also kill the glove compartment light, etc. (the best i came up with is fuse # 17).

really aggravating.

Your thread was moved into the stock 2002-2005 section. Have an auto parts store or alternator rebuilder bench test the alternator outside of the vehicle.

If voltage on battery terminals (when engine started, with all headlights and heater fullspeed on) between 13.5 and 15V, you really have battery charge on. In this case you can try to change voltage regulator.

Also you can look my reply to phouse's message

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..

Unhappy "Check Charging System" Constant beeping and battery light

Hello,
I am going crazy with this constant beeping every 15 seconds in my vehicle. I cannot even tell you how long I have been dealing with it, but it is constant now. It goes off every 15 seconds. My alternator has been replaced. My battery has been replaced, Autozone says everything is charging fine. I am at my witts end. Please help.

After reading your last statement I am confused about what fixed your problem. My email address is saenz.janie@gmail.com please get back with me if you can.

Yesterday put in a replacement alternator, because of a noisy bearing. The replacement had all of it specs showing it passed testing outputting 152 amps at 6000rpm and 105 amps at 2000rpm. I put it in and my scanguage showed 14.2 volts at idle, yet my battery light was one. Check all of my connections and could not figure out what was wrong. Napa ended up giving me another replacement alternator, I put that one in and the battery light went off. I don't know why the other alternator gave a battery light. I suppose the regulator was not doing something right, even thought 14 volts were showing.

Don't put it pass the replacement being faulty.

quit using crap parts and that might sort out the problem, alot of these cheap alternators leave low voltage lights on in a variety of vehicles, go get a motorcraft and see what happens
