When it happens, I can hear a difference in the load on the engine (slight, but it's there). When running, volt meter on the battery reads 14.5v +/- and when not running it reads 13.3v +/-. Could this be the same corrosion issue with the regulator?

I hate necro'ing a thread, but it seems I'm having a similar issue.

I just replaced my alternator (I'm on my fifth one...in about 2 years.) I've replaced the battery recently. I'm getting the battery light, my airbag light and my power steering light on.

All 3 lights will go away after awhile, but whenever the power steering light comes on, even going 40mph+ the wheel will lock up, and I can't move it. It's becoming more of a safety concern now.

I've also noticed that my headlights will also be quite a bit brighter.

I've had the alternator and battery tested in the past week and everything is "functioning" as it should. All the numbers match up to what should be standard. All the mechanics I take it to, think I'm crazy, until I show them the videos I've taken of it happening.

I've also recently blown threw a new set of headlights. All 4 filaments were burnt out, but no fuses needed to be replaced.
