I have a 2007 Nissan 350Z and there is a trim bar inside of my car that feels electrified. I even touched my tongue to it (please, I know) and I can feel electricity. It's similar to if you have ever taken a 9volt battery and touched it to your tongue (older brothers).
Here are some parameters. If the ignition is off and the doors are open with I can feel it. If the ignition is off and the doors are closed, I don't feel it. If the ignition is on I feel it with doors open or closed.
The trim piece is fake chromed. I thought plastic underneath the fake chrome look but I'm not sure.
Everyone I've asked just stares at me and shakes their head. They usually follow it up with something like, 'that's weird'.
I've had my battery ground checked and made sure there's no buildup on the batter terminals.
Any tests I can do or have done with a multimeter to figure it out would be awesome!
Here is a picture of the trim. It isn't my pic but this is it. Got it off the web.
