Back to the original thread, my alternator absolutely is working as soon as the engine fires. My voltage goes from around 11 to 11.8 as soon as the engine fires.

As far as flashes are concerned, I have the latest flashes and my truck is starting perfectly at around 25 degrees. No buzz, no noise, just crank for 2 - 3 seconds at start, and then high idle automatically after about 2 minutes.
