[QUOTE="gunz4me, post: 5658434, member: 596464"] I once had a replacement alternator that generated noise through the stereo system whereas the factory alternator worked fine. Turned out the replacement had a bad diode in it that was feeding noise to the electrical system [IMG]//content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif[/IMG] Of course, that is a rare case, unless your alternator happens to be on its last legs. In some cases, I have seen the factory ground cause noise when connected through the harness, but grounding to the metal behind the dash didn't. Regardless, ground loop noise is a pain in the *** to track down. [/QUOTE]
