hey everyone going down the road and battery light comes on looked for loose connection could not find anything wrong and also charged the battery. is it the alternator if so how do i fix thanks and have a great dayy

 

Check you fuse first, if they are good then the alternator is bad. Go to a parts store and have them check your battery and alternator.

 

I found this on how to test your alternator on the vehicle.
They have a kit that bypasses the computer and makes it an external regulator like it used to be. The kit is ERCKFRM
How to test your alternator on the vehicle:

To check to see if your alternator is working, unplug or remove the two field wires from the back of the alternator. Then ground one of the field terminals on the alternator and jumper the other field terminal to the positive battery post on the back of the alternator. It does not matter which terminal is grounded and which one get positive power. When you connect the ground and positive wires to the field terminals you will get a small spark, this is normal. This is by-passing the voltage control and will cause your alternator to run full blast, if it is working. Put a multi-meter on your battery and run your engine on high idle, do not allow your alternator to charge the battery much over 16 volts. If you find that your alternator is charging when you do this procedure, but does not charge when you connect it back to the computer, this kit will get your alternator working and charging at the proper voltage. The voltage regulator is preset at 14.5 volts. If you want to adjust the voltage regulator you use the screw on the back, but be sure the metal case of the voltage regulator is grounded while you adjust it.
