Hi Keith
I bought 12 volt generator brushes for VW in Florida at 
Advance Auto Parts " no shipping charge"

Driving around town now in the rain, lights on, wipers on,  and things are
getting worse again.  No COLD generator light when I  first start it like
before but now the electronic Bosch regulator is  starting to give an idle
light, and this morning when I arrived at work I  had to get it up close to
3K RPM with the lights and wipers OFF to get the  generator light out!  Now,
it IS charging at those RPM's even if the  light is on but at idle its 
almost
as if its not full-fielding the  generator when it should. Drove home, nice
bright light even though it WAS  charging and the system voltage was good,
then, about half way the light  would go out but a little while later its on
again and now its NOT charging  unless I get about 3K RPM.  Got home,
squeezed the brushes on the  generator and all was well, so now it's the
generator again!  These  brushes are new and not worn down and this is one 
of
the 2 generators Ive  been using with no problems for 20 years.



Is it possible that  the regulator is damaging the generator?  This 
generator
still looks  fine and both brushes still look/feel new but needed a squeeze
to make good  contact again after only about 1000 miles on them



I will say  that I got 2MPG MORE on the return trip from PA with the 14V and
although  there was some tail wind involved for about 60 miles that wouldn't
have  accounted for all of it.  I also noticed that it was detonating on  
the
hills though, something I haven't heard before with the new stepped  heads..
Should I adjust it a smidge richer or just go up to 89  Octane??

Anybody have a set of 12V generator brushes they'd sell me  without charging
me $10 in shipping to send them?  I need to rebuild  another core I have if
Im going to feel good about the invasion  trip.



Thanks

Keith
