I've noticed lately that while night time driving, the headlights dim , like
in power surges.  I thought it was maybe my imagination, or the result of
driving on un-even roads..however.. today, I got in, started the engine, and
the interior coolling fan was on.  I noticed the same thing...
surging..while the car was sitting still, with just the engine turning over.
So, there is definitely a problem there.  The pulsing/surging is too regular
to be a belt slipping.. could it be worn brushes?
I'm not that well up on these things, and I live in the wilds.. so any help
would be appreciated.

Thank you

Nichollette
