ever since ive had my SC400(about 4 months) I have CEL and a trac OFF light that both come on, havent got the car scanned yet and its obd1. Sometimes I would start my car its not on and sometimes its already on. once I start driving it comes on and stays on. Comes and goes. I don't feel any power difference or anything. If I turn it off and on again it would go away but comes back. Also to note that has some sort of voltage issue. Whenever I give it any throttle the lights like headlights and interior lights brighten, press on the brake or use turn signals. it dims and comes right back. I have already replaced the alternator, battery, battery thermals. Its got to be some ground but I don't know which one. Maybe that CEL has something to do with it? IDK

Ive checked almost all the grounds and they seem fine to me, I have replaced my battery terminals, but I am thinking its the cables itself. this all started when the previous owner installed a radio, amp,speakers,alarm system. Which i have mostly fixed.
