VGA Cable causing engine noise
So I finally troubleshot my noise (cross between white noise and alternator whine) to be the VGA cable.
I have a 25' VGA cable (although I wish it was 15' now because I've got tons of extra wire and it's a little fuzzy) running from my dash to my trunk.
What's strange, though, is that I have the VGA cable running with the keyboard (PS2) and USB cable. Neither of them cause the noise - it's only when the VGA cable is plugged in, so it is getting interference somehow..
I'm wondering if it's because my LCD is grounded to a different spot (12v cigarette lighter for now) or if it is just getting some disturbance from any of the 10+ wires it goes near which run inside my dash, down into my kick panel, and down through the door sill to power other components of my car, such as taillights, trunk release, brake lights, fuel pump, and other various rearward car components...
Which do you guys think (as a point to begin troubleshooting further)??
I guess I could unplug my LCD power source and see if that makes a difference.. maybe it IS because of a ground loop? (does that make a ground loop?)
