Alternater replaced 3 time an still bad!

Hi if the alternater has packed up then the ecu has put these falts up becouse it sees a falt in the system ,get the alternater fixed and then the other falts should wright there selves,hope this was some help.

Hi,if you are talking about the red light for the alternater is on then it means that the car is not charging,and the fuel light is to do with the sender unit in the fuel tank.
to see if the alternater is working ok you need to put a mullty metre on the battery and see what the voltidge is,get some one to press the frotal pedal you should see the reading jump up from 12v to about 14v approx,if the valtidge drops bellow 12v or dose not increase then the alternater is falty replace,
then to check that the fuel sender is working find the wires on the fuel tank take off and join together switch on ignition if the fuel diyal dose not go to full then replace the gauge if it dose go to full replace sender.
hope this was some help,all the best.

If the alternator is on the top in the open, just loosen the alternator bolts a little bit. Then push the alternator to loosen the belt to remove it. Do the opposite to put the new belt on.

If the alternator is buried under a lot of other things, it's a lot tougher job.
Hope this helps.

replace the voltage reulator some have it internal of the alternater if so then you need to replace the alternater

There might be a short between the alternater and ground.
Check wiring
Disconnect battery and alternater wiring from the back of the alternater and with a multimeter check for continuity between the BAT stud on the back and the alternater housing.There shouldn't be any.

Just cause its a new alternator does mean it should work. I would check the charge when running cause it could just be a bad alternator.

If the alternater light has come on in the car that means that the alternater is bad and you need to replace. You can also have it checked at your local auto parts store if you would like.

Good luck

Alternator knocking ????is the alternator light on is it charging as is almost impossible to get a knocking out of a alternator and it still charge at the same time.
Start engine ind get a small plastic tube and put it on the alternator and put your ear to it and you should hear the noise real bad.
And you should feel it getting real hot after run for 3 minutes if not its not ALTERNATOR
