I change alternator 3 times 6 month and no charge again i need help for fix

batteries will self discharge over a period of time especially in cold weather
however 3 batteries replaced in 6 months raises issues
first question is why would they not charge up on a charger or a run in the vehicle
second question is the battery of sufficient size to run the electronics
have you had the alternator bench tested to check for correct out put, regulator operation and rectifier problems
check drive belt condition and tension
the wire could be a ground wire but I would think that if it is significant then something would not be working correctly

Very strange question...
The alternator is charging the battery.
They work together. Did you replace it yourself or by a car mechanic? Is the belt OK? How do you know the alternator is bad? I'm so sorry, but this is just not enough info, I'd be very happy to help you, but I'd need a bit more info.

yes it is possible

i believe there are 2 alternator's for that 5.3 i think you need the one with the higher amps. I had the same problem and went with the higher amp alternator and i have not had a problem that was 3 years ago.

How many accessories do you have plugged into the power ports? Do you have a lot of stereo equipment in the vehicle? Do you only make short trips with the vehicle? Too much load on the system from accessories (Cell phones, computers, GPS receivers, stereo equipment etc.) will cause batteries to drain. An alternator will provide enough power to run all of the stock electrical load and maintain a charge on the batteries. However, if the electrical load is greater than the alternators output, power is drawn from the batteries as well. Combine that with constant short trips and the batteries will never have a chance to be recharged.

CODE 12 STAND BY MEMORY POWER LOST.WHAT IT SAYING ECM LOSING MEMORY BECAUSE LACK OF POWER.POSSIBLE CAUSE TO YOUR PROBLEM COULD BE OLD WORN OUT BATTERY CABLES CAUSING POOR GROUND AND HIGH RESISTANCE IN CHARGING CIRCUIT.YOU COULD HAVE WRONG AMP ALTERNATOR AND BATTERY WRONG COLD CRANKING AMPS.MAKE SURE ALTERNATOR BELT TIGHT AND CHECK ALTERNATOR BATTERY FEED WIRE AND ALTERNATOR FIELD WIRES FOR DAMAGE OR LOOSE CONNECTIONS.CHECK ALTERNATOR FUSE. WITH ENGINE RUNNING ALTERNATOR OUT PUT SHOULD BE 13.5 TO 14.5 VOLTS IF NOT ALTERNATOR NOT CHARGING.

check and see if oil is dripping inside of alternator and if it is it's shorting it out...

YOU NEED TO THAKE YOUR CAR WITH A ELECTRIC SHOP TO CHECK IT IF YOU CHANGE THE BATERIE AND THE ALTERNATOR TO YOU CHECK IF THE ALTERNATOR BRAND CHARGE THE BATERRIE SOMETOIMES WHEN YOU CHANGE THE ALTERNATOR OR REBUILDIT SOME PARTS HAVE PROBLEMS CHECK THE ALTERNATOR AGAIN WITH A VOLTIMETER TO CHECK IF CHARGE BETWEN 14 VOLTS OR 12 VOLTS

What engine do you have? Where did you buy the alternator? I want to help you but need more info. Get back to me OK. John
