For well over a year, I have been hearing this squeaking sound coming from the generator area. I thought maybe it needed a bit of oil, but that never solved the noise problem. While on the tour last weekend, the noise got louder. It turned out that my pulley was coming apart. I have since ordered and installed a new one, and now that noise is completely gone.
