It's a "static" type noise that relates to my engine RPM. It seems to be getting progressively worse. I hear it when I open the squelch on my mobile and on some freqs of my FM broadcast radio. My mobile radio is connected directly to the battery. Today I changed the alternator hoping I would luck out. I don't know how old it was and it wasn't going to be hard to replace so I went in that direction. No joy. The spark plugs aren't as easy to get to in this V-6 so I didn't do that first. Perhaps spark plug wires next?</div><div dir="ltr">Thanks for any insight you might send my way.</div><div dir="ltr">Cheers,</div><div dir="ltr">Anthony</div><div dir="ltr">951-623-3400</div></div></div><div><div style="font-family:Helvetica Neue,Helvetica,Arial,sans-serif;font-size:13px"><div dir="ltr"><br></div></div></div>-- <br>
