Hi Everyone,

I have a 2006 350Z enthusiast and there seems to be some electrical issues with it. There are occasions when I turn the AC on and it seems that the idle will dip down to around a rough 200~150rpm but then shoot back up. At the same time when the AC is activated the dash lights will flicker. The same things will also happen when the windows are rolled down.

There was a previous issue a few months back when the car refused to start or have any power. The battery was tested and showed a full 12v, but when connected to the car and the ignition turned, it would shut off all power. The battery leads were re-tightened and the car luckily turned back on and I haven't seen the problem since.

What is the issue? Are these symptoms related? Any help or insight will be much appreciated. Thanks for reading and I hope to hear from you guys soon.
