My 04' ford taurus check charging system light keeps coming on, I have replaced the alternator and a new battery but light keeps coming on???

I have replaced the alternator and battery, had the charging system checked out at Les Schwab and it checked out good, however the check charging system light keeps coming on. Is there anything else it could be that I haven't checked yet??

SOURCE: New battery & new alternator, still not charging...

Take it to another auto parts store to test to verify.
If you put a voltmeter on the battery when the T+C was running, it should read 14-15V.
It could have a bad diode. If this is the case the alt. will be pumping out AC instead of DC. This is BAD. Batteries do not like this and the battery will fail because of it.
Be careful in those 'auto parts stores'. I have found that they employ alot of 'kids' who know little about how a car works. Try NAPA. They are much more knowledgeable and professional. But they cost alittle more.

I have 2006 ford taurus check charging system and battery light on what's the problem help me please


Battery Light usually means the alternator is not charging correctly and needs to be replaced. Check charging volts, it should at 14 volts or very close to that number. If the number is low below 12 then the alternator needs to be replaced.

Note: A bad alternator can damage the battery & vise versa

Check charging system light for 2006 ford taurus


You would need to check the connections on the back of the alternator with a meter.
You should have battery voltage on the large wire and on the orange yellow wire.
The other two wires involve the engine computer which turns the alternator on after the engine starts.

My 95 Taurus SHO's "check battery" light had been sporadically coming on. I threw in a new battery. Now it's on all the time. Should I throw in an alternator now?


Hi:
The check battery light means that your car is running off the battery, and the charging system is not working. A good plan would be to recheck your battery cables and connections, then remove the alternator and have it checked. Most autoparts stores will do this for free. The alternator is the most likely suspect!

Battery light comes on and it also says check charging system


Hi. If this light comes on when your alternator is not making electricity and the car is running off of battery power alone. you'll either need to replace your alternator belt or the alternator, but before you do this, go ahead and check your battery connections. Sometimes cleaning the connections will fix a charging problem.

Why does the battery light keep coming on after


The battery light indicates insufficient voltage. I would recheck all the battery connections to be sure they are clean and tight. I would also have the alternator output tested, since the light will come on if the alternator is not providing sufficient voltage to keep the battery charged. Take the vehicle to an autoparts store and they will test the battery condition and alternator output for free. Sorry for your trouble and I hope this helped, Best wishes.

Ck charging system light and battery indicator light came on twice and stayed a few minutes on 06 taurus


Check for damaged or corroded wires on alternator. Also check connection to alternator, take off and clean. Alternator may be on it's way out. You might want to get it tested at garage or replace if problem persists.
