Here's what I hear from Ray, who was taking photos of the Poteet and Main car in the pits:
The car's data logging showed that on the down run, about an hour ago (now), the alternator was not charging the battery. So they didn't have enough to start the car for the return. They brought out a small charger/small generator to top off the in-car battery for the return, and it was charging well. But they didn't have enough to start the car. So they brought out a bigger charger (jump starter) to start it -- but that drew so much that they stalled the little generator. So they ran for and brought out a bigger generator, which made enough for the big charger to start the car, and George left. But then -- when the computer starting pulling big amps during the run -- there wasn't enough juice and things came to a halt.
At least -- that's the theory that we'll offer for now. The car will be back in the pit in a little while and maybe Ray will get some more story for you. He took about 700 photos (his words) while the car was down here -- let's see what he says when he posts. In the meantime -- nothing going on for a while. Go have a cold drink. Gentle winds here in the pits - about 3-5 from the north, and temp about 75. Gee, you oughta be here -- Nancy's enjoying the weather, just hanging out in the sun and getting some rays. I'll look at her for you, guys.
