Hi, from what I find searching, I am not too clear on the operation of the
dash idiot lights I've been seeing all too much of these past few days.

  Right now, I am running without a working alternator, having recently had
it begin to fail (flickering , then full time Alternator/O2 sensor indicator
lights, engine running)  After messing around with the alternator, the
Voltage regulator/brush pack (if my terms aren't exactly right, I hope they
are understandable) and swapping all kinds of batteries in and out to get
back home, I have a new alternator coming tomorrow.
   But right now, when I turn on the key, the indicator lights for the
alternator and the 02 sensor do NOT illuminate.  Before I started messing
around with the alternator and the brushes, the ignition switch activated
the warning (idiot) lights when in the on position but without engine
running.  Then my alternator warning and 02 sensor warning lights would
briefly remain on after engine start until I moved the rams up one
time...that would 'unlight' them.  Right now, I no longer get any lighting
of those two..All the remaining warning lights (Oil P., Seat belt, E-brake,
turn signal, high beam) they work as they should.
  So did I mess up a circuit that activates the preliminary lighting up of
the Alternator and O2 sensor indicators?  Or when I replace my faulty
Alternator/Voltage regulator will those lights resume working?
