[QUOTE="AlterEgo99, post: 6017636, member: 610253"] Sometimes that is the only way. There are several good sites out on the net that walk you through step by step to troubleshoot alternator whine: [URL="http://www.caraudiohelp.com/newsletter/alternator_whine.htm"]http://www.caraudiohelp.com/newsletter/alternator_whine.htm[/URL] [URL="http://www.termpro.com/articles/noise.html"]http://www.termpro.com/articles/noise.html[/URL] I've used them both to great effect...at the very least they help you isolate the source of the noise and then you can start trying different ways to defeat it. It beats guessing and spending 10 times as long trying to correct it. My alternator whine, as minimal as it was, was finally fixed when I performed the "Big 3" and removed the OEM chassis ground from the block to the chassis. I created a new grounding point and when I disconnected the OEM one, poof, whine gone. [/QUOTE]
