Ipod Interference (Whining)

[mwrbunny]

hmmmmmmmmm........(with a blank stare)
I guess what you're suggesting is that I have a partial failure in my ignition system, and thats causing the whine.

....I wouldn't even know where to begin to solve that issue.......

apparantly, this isn't a common issue with the Ipod interface, and there isn't an equally common "fix" which is what I was looking for. Thanks for the replies, and I'll just see what pans out. Maybe next time it's at the dealer I'll have the ignition checked out just for sh##s and giggles...

I just re-read my reply and noticed I said "alternators" when I should have said "distributors" in the Corvette shielding example.

Spark plug wiring is usually shielded, noise suppressive but if you've got a cracked wire, coil, or bad plug then you'll notice an increase in noise on audio equipment.

In some cases you can pick it up outside the vehicle on the AM spectrum using a radio. If you have a long wire connecting the device to an audio input, that will sometimes act as an antenna.

One quick and dirty way to check for damaged ignition components is to observe the motor running in low light or darkness. Look around the spark plug boots and ignition coil(s) for any arcing. If you see a spark jumping then you've likely found the source of your interference.
