Generator rebuild follow-up #2

I found an additional side effect to the generator rebuild project I thought I would mention.  The generator has always charged fine and the gen light has always behaved as normal, but!  I had the stereo connected to a full time 12 volt lead under the dash.  It works fine, but it almost always would lose it's presets and the clock would reset.  This happened after I restarted the bus.  Just shutting it down had no effect.  This is where it gets a bit loopy; After the new brushes in the generator, the stereo has not lost its presets even once.  Hmmm.  Maybe cleaning up a ground, bumping a wire, or the new brushes did something good in there.  Oh well, Happy Camper I am.
