Dimly Lighted Battery Indicator Light

[yuri2002]

Okay, I got a 07 Toyota Yaris with 135,000miles. I just replaced the alternator two days ago. The alternator has been making whining noise nonstop for the last two months, so finally I found the whining noise coming from the alternator bearing. I had replaced the belt last month prior to replacing the alternator. So today, after about 250miles with the remanufactured duralast alternator, the battery indicator light stayed on, but the light is very dim. I have seen a brighter light when the original toytoa alternator was in the car. (The INFAMOUS voltage regulator issue). I tested the battery when the car is running, it's at 13.85V. The belt looked good, nice and tight. I am mystified why this little bugger is giving me such a headache lately. Any suggestions what to do next? Thank you
