Hey guys, I'm new to this page and this is my first post. I bought a 2006 mustang gt on 7/17/2016. It has 96k miles. The car is mainly stock, except for the rims and tires. With that said, I finally had a chance to release all the HP this pony has. When I did, I noticed that when I reached 4500 rpms, all the lights, AC and the stereo turned off. This lasted for a few seconds and then they all turned on again. First I thought, maybe the initial jolt of the car might have caused this, maybe a loose cable got moved more. So I tested my theory. I got on the freeway and slowly took 3rd gear all the way to 4500 rpms, and everything turned off again. Idk where I should start. I don't get a "check charging system" message like other people. Keep in mind that the engine is still running/accelerating when this happens. Thanks in advance.
