New car, stereo not installed. Everything works fine. Hey, I will plug the stereo back in! Plugged in: Stereo acts funky; Dome, fuel, and tach start to oscillate. All go out, including turn signals. I pull stereo, replace turn signal fuse with a 10 (wants a 20, I only had a ten), all systems back up. I take the stereo (and the car) to a decent audio shop and explain the situation. They bench test the stereo, say its bad (which I believe), so we put in a new deck. Couple miles down the road, all the same systems go down. I put in a 20A thinking that is the difference (I had a 10A) but it blows just the same. Obviously, stereo is interfering with the dash (aftermarket gauges, by the way), but I am no where near a wiring guy, so I any advice is appreciated.

had the same situtation happen to me, although the stereo was removed which caused all my problems. FIX IT NOW, NOT LATER! I say that because I drove around with dim lights thinking they were just that way 30 years ago, and then it just started dying on me, and I couldn't start it at all! So, a voltage regulator, battery, and alternator later, I was still not going anywhere!

I threw out a whole weekend just sitting in the car ripping all the panels out to find wires. This sucked, it was a frankenstein job done by the guy before. I must have pulled a groccery bag full of garbage out when doing this.

I then put in my own stereo wires and ran the power straight to the battery, cleaned all the wired I could find in general, especially the grounds, and put in a deck. This pic is of what the center area looked like before I went in.
