Hello my name is Christina I have a 2005 Ford Explorer and my check charging system light keeps on coming up. I changed the alternator 2 to 3 times already I have had the car for about one year and half. The last time I changed my alternator was about 5 months ago so I don't know what can be wrong with the car now. Please help. Thank you

Hopefully you can take the car back and have it repaied under warrenty.
Things that are a part of getting a charge in the battery are as listed below.
Alternator ( it makes the voltage to run car and charge the battery)
Regulator (sometimes it's internal to the regulator, sometimes its a seperate module)\
(it controls the prober voltage to run the motor and accessories, while keping the battery voltage up to full charge)
Alternator belt( turns the pulley on the alternator to make the alternator produce voltage)
Belt tensioner( a spring force if the tensioner keeps the belt pulled tight. so it does not slip when the pulley spins)
Battery connections and cables(the battery need good connections and must be in good condition to properly handle the charge voltage from the alternator)
Battery.( the battery could be bad from over voltage charging or just age )
Super Hot weather is as hard on a battery as cold weather.

Good luck

any,or a any combinations of these items could cause your problem.

It seems like there is most likely a bad connection between your alternator and your battery I would look into replacing those wires. That is far more likely than that many bad alternators.

My 2005 ford explorer xlt check charging system light keeps coming on. I just recently within 60 days ago replaced the alt AND the battery. Thought that solved the problem then about 2 weeks later it came...

You need to check the out put of the alternator. In general the alternator should put out 13.5 to 14.5 volts. I would say go to where you bought the alternator and have them check the voltage. If check engine light is on you should have a code get them to check the code. Most auto part stores where I live will check your code for free.

I recently had a new alternator installed in my 2005 ford explorer. The check charging system light keeps going on and off. I understand that there may be loose connections on the alternator and I am...

first, disconnect the negative battery terminal. then there is a alternator output cable which is attatched to the alternator with a nut, covered by a rubber boot, tighten the nut. then, there are 1 or 2 electrical connectors, wiggle the to check for looseness. also, they should not pull out unlees you deprees the locking tab. if they pull out, someone damaged the tabs. or it's possible the alternator is defective.

My 2005 ford explorer check charging system warning light

if charging light is on w/ engine running,the fault could be the alternator or another component of the charging system.remove, clean and tighten battery post connections to check for alternator output,use a volt meter or multi-tester set to 50 Volts DC,w/ tester on battery terminals it should read 12 volts W/ engine off;13 to 14 volts w/engine running.if voltage increases when alternator is spinning,suspect battery

96 Ford explorer. 4x4 lights blink.

possibility you have a bad battery that will not hold a charge or an alternator that is not charging the battery to it's potential, might want to get it checked in a shop....or try changing the battery....if it keeps up, it could be the alternator.....hope this

"check system charging" is coming on at high RPM's

You have an alternator problem, have Kragen auto or a store like it test the alternator for proper operation, it's free.

Check charging system

Do you have gauges on this car also?
If so, you may have a problem with what is called a "current shunt" resistor. This will prevent the car from recharging the battery....accordianman
