Weird charging system problem

[txrocco at sbcglobal.net (ATS - Patrick Bureau)]

have you checked your alternator brushes? (ie: change the voltage regulator)
if they are tired (or the voltage regulator is on the way out)they may not
provide enough power to recharge the battery, that would be my first
instinct and part to check, autozone carries these for a few dollars.

=>I recently finished getting a working engine in my 84, and it
=>runs, but the
=>alternator doesn't charge the battery.  If the car is running, it powers
=>itself off the alternator, but the battery doesn't charge.  I
=>know it's not
=>running off the battery, because a couple of times I drove it 2
=>hours home
=>from Dan Bubb's place, and never lost power the whole way home
=>like it would
=>if the fuelpump, coil, etc. were running off the battery.  The
=>battery life
=>is dependent on how many times I start the car with it.  After
=>checking the
=>Bentley diagrams, I can't see how this could occur, because the
=>alternator
=>goes to the battery before going to anything else (as far as I can tell.
=>I'm still not a whiz at those diagrams)  I know the battery is
=>good, because
=>I tried two known working batteries, and the problem stays.
=>Right now I'm
=>charging the batteries with a plug-in charger until I figure this out.
=>
=>BTW, it's an early 84 with the single rubber alternator plug
=>(rabbit style)
=>instead of the stud-terminal.
=>Does anyone know where to get the wiring harness for this type of
=>alternator?  I'm almost to the point of tearing it all out and
=>replacing it
=>all.  :P
=>
=>Thank you so much in advance for any insight.
