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

Sluggish & electrical problems after new alternator & battery put in


Sounds like the new alternator is not charging the battery. Once the battery drops below a certain level the car can't keep its components (on board computer) running. The ignition is now running off the battery which is fading. Soon the car won't be running at all.

As already suggested, check belt and new alternator.

The charging system on your vehicle is computer controlled . Your vehicle is a rolling computer .The instrument cluster has a microprocessor inside , there is also a body computer ( SJB ) smart junction box , Engine computer etc... they all communicate on a serial data network , C.A.N - controller area network . It's hard to know what's wrong when you don't know how it works . There could be codes stored in the computers , these will not always turn on the check engine light .

Battery light stays on


the battery light has nothing to do with the battery itself, it is indicating that there is a problem with the alternator that charges the battery, most likely a defective rectifier bridge diode has failed.
