Randy, try spraying water on the serp belt when its whining. If it goes away, then its the belt either not tensioned correctly or bad belt. I dont think its that though.
One way to tell if its the alternator bearing starting to go is drain the battery slightly. Headlights on for a few minutes, blower motor on high. Keep lights on, turn blower off so you can hear, and when you start it throttle it to ~2k. Usually they'll squeal under increased load if the bearings are starting to go
