OK HERE IT IS..MY BATTERY WAS NOT GETTING ANY CHARGE..I WOULD PUT A NEW BATTERY IN THEN AFTER A LITTLE DRIVING MY CHECK ENGINE LIGHT WOULD COME ON AN VOLT METER WOULD READ 0..I CHECKED TO SEE IF MY ALTENATOR WAS GETTING VOLTS .ON I THINK THE NUMBER 2 PIN WHICH I WAS TOLD WAS THE HOT WIRRE FROM THE IGNITION ..I WAS GETTING NO VOLTS..SO I WAS TOLD TO JUST RUN A WIRE FROM THE NUMBER 2 PIN TO THE BATTERY AND IT WOULD FIX IT..WELL IT WORKED.I WAS JUST WONDERING IF MY ALTENATOR LIFE IS GOING TO BE SHORTENED BY THE BY PASS?AND IS MY BATTERY GOING TO BE OK?
