Another update.

Yesterday I had to drive pretty far (240 miles round trip on the highway).

I had the OBC displaying voltage the entire trip. It read between 13.6 and 13.9 the entire trip.

Still no warning lights and I haven't installing the replacement alternator yet. I'm wondering what in God's name caused all those warning lights. I've put over 300 miles on the car since the lights went off without a problem. Of course I haven't really stomped on the gas pedal since. Could something have happened when I got on it the other night that tripped all those warnings?

I did go in the cargo area, noticed that when I installed the new battery in the dark last week, that I didn't run the wires for the air pump under the brackets in the back. Could the weight of the spare sitting on the wires for the air pump have caused this? Seems that ever since I moved the wires under the support brackets I haven't had a problem.
