I *think* I may have found the source of the iPod troubles that I was having. It seems that when I have the power filter connected in with the Key/Acc line, it almost holds a charge of sorts, keeping Key/Acc high for a little while (maybe 1/2 second when the radio is on) after I flip the key to off. I’m thinking this bit of extra charge there is possibly keeping the iPod from properly thinking the power has been removed.

I tested this by:

1) Leaving the radio on and quickly switching the ignition from accessory to off. Radio stayed in for .5 sec extra.
2) Cut the line running to the filter (and thusly the iPod adapter).
3) Repeat step one, observe that radio does not stay on for .5 sec extra.

After dinner (and some King of the Hill) I’m going to throw some laundry in, then reconnect the iPod adapter, sans filter, and see if the problem still exists and if there is any additional noise. If no noise and problem is gone, I’ll be a happy Steve. If the noise is still there, it’s time to investigate 0:0 transformers for coupling purposes. I’m not sure how to set this up… I’m not sure why the Radio Shack filter seems to hold a charge. Maybe there’s a cap in there to prevent voltage drop? Not sure…
