I replaced my battery,terminals about a week ago. I bought a regular 530crank amps battery. B4 and after the battery whenever the car is ideling around 750-780 rpms(as stated in the book) the lights dimm pretty bad. Whenever you give it gas the lights brighten up. now it's not that noticable but it bothers me like a mofo. Also when Im closing my windows or sunroof the lights dim pretty bad. I cleaned all the grounding points and cleaned the ends of all the ground wires. help!
