So I'm finally starting to get to the bottom of my alternator not charging the battery. I purchased a new alternator with an internal regulator. I then made the connections to remove the voltage regulator (blue to brown and yellow to orange). Still the alternator was not charging the battery. Finally, I traced the brown wire, which used to go to the regulator, inside the car and found that it did not lead anywhere and was just open hot lead. My understanding, from wiring diagrams, is that the brown wire needs to be hooked up to the ignition switch. Getting to the ignition switch seems like a difficult task. Could I just connect it to an ign post on the fuse box?
