I need BOOOOST!!!!!!
last week i noticed that my gauge cluster lights were flickering from bright to dim in rapid succession. i had a feeling that my alternator was about to let go. for the most part it did not flicker when the car was cold and usually would not start until i started to actually put the engine under load. the flicker was very noticeable in the headlights at night too. after a week the lights just went dim and never flickered back up and after about a mile or two the battery light comes on. the alternator quit charging... i made it home before the battery died, pulled the alternator and took it to advanced to have it tested and replaced under warranty and the alternator still tested as good. this leaves me with two conceivable options that i can see. either the pig tail is bad or the ECU/PCM is bad. just looking for confirmation or any other ideas as to what it could be. the plug that hooks up to the alternator looks just fine. the wires are not working their way out of the back side of the plug or anything. there is no copper wire visible anywhere from the plug back as far back in the wiring harness as i can trace it. there is no corrosion or anything visible in or on the plug. im going to go up to ford today and order another pig tail anyway and hope that there is something wrong with it that got past me but i dont have high hopes.
