[QUOTE="akheathen, post: 7882237, member: 629234"] is the whine the "alternator whine" playing through the stereo, or more of a bearing squeal? also, check your battery, and alternator plug. you should have a load-sensing ecm function that bumps the charging after a large load, like starting, and then runs only on-demand for economy. i had a few spikes in my system, but wiggled the plug a bit and it smoothed out to a solid 14.4. usually, if it is real noticeable, like in the lights, than there is a connection issue, or weak battery [/QUOTE]
