thanks for the info!

curious as to why the brushes have been targeted as the source of the noise, as they've been replaced and the armature cleaned, etc. AFAIK, they may cause some noise, but rarely squealing.

IME, it's always been the generator's bearings or bushings that squeal (the generator may have a couple of oiling ports, BTW), or perhaps the belt or any other device connected to it. good luck!
