Sorry, didn't read beyond doo-dad.

To my knowledge, the alternator idiot light must have continuity in order for the alternator to charge. But I've never verified that rumor nor have I faced the problem myself, so I can't share firsthand experience with you.

It's possible that you sinply started out with a very well charged battery.

I had bad alternator brushes in my '90 when I bought it last year and drove it almost a month (about 350 miles) before it quit on the road. I got a lot from that battery before it died.

Someday when you're looking for a good experiment, measure your battery voltage at idle. Then unplug that red wire and re-measure the voltage at idle. See if it drops from 14 volts to 12.5 volts without the red wire.
Write up the results and report back here...
