MAKING OF CHARGER or bad contact FOR CHINESE PHONES


THIS MAIN PROBLEM IS WHEN U CHANGE UR CHARGER.
IN ANY CHARGER OPEN UR CHARGER'S CHARGING CONNECTOR THEN REMOVE THE WIRES FROM CONNECTOR.
RED,BLACK,GREEN,WHITE REMOVE RED & BLACK WIRE.
CONNECT CHARGER WITH PHONE REMOVE BATTERY
SEE - & + OF PHONE
CHECK NEGATIVE CONTINUTY WITH MULTIMETER TO THE CHARGER CONNECTOR POINTS
SOLDER BLACK WIRE TO NEGATIVE TRACED
SOMETIMES IN SOME SETS POSITIVE IS ALSO GIVING CONTINUTY U CAN ATTACH RED WIRE.
THE VOLTAGE IS OK BUT IT WILL NOT DISPLAY CHARGING THEN U HAVE TO TEST BY INSERTING BATTERY TO THE PHONE
BY ANY WIRE OR TWIZER CONNECT ONE SIDE TO RED WIRE CONNECTED TO THE POINT THEN SHORT OTHERPINS ONE BY ONE BY THIS WIRE.UR PROBLEM IS SOLVED

IN BAD CONTACT CHARGER PROB. U JUST HAVE TO TEST RED WIRE TO OTHER POINTS.
I TRIED THIS MANY TIMES 100% SOL.
THANKS
