Default UPDATE

Alright, so I've been messing with it over the past couple of days and have found out some things about the noise. I disconnected the antenna from the back of my casette desk (stock) and ran the car. For around 10 minutes, there was no noise, however it came right back. So it'* no the antenna causing the interference (damn). So I plugged the antenna back in, obviously touching the metal part of the antenna lead and the noise was again gone for around 10 minutes, and came back. Why? I also noticed this when I was messing in my trunk trying to find the solution to this increasingly annoying problem, and touched the chassis, the noise again went away for around 10 minutes. Is the car somehow building up resistance, then it has to go somewhere? If it'* not coming from the antenna, then where? I'm totally confused by this, and am regretting putting in that 10 disc cd changer more and more every day.

I did strip two wires when putting in the cd changer, the 12 volt constant and the ACC, only about 1/8", and have since put black eletrical tape around the missing insulation. Could this be causing the problem? How can I shield the missing insulation more? Or is there a ground missing somewhere? What about the alternator, which I think is bad anyways because of several underlining reasons. Thanks in advance guys

Whining is usually from a bad ground in the system. Try redoing the antenna'* ground in the trunk behind the carpet. Sand down or wire brush the metal till it'* bare, maybe use some Dilectric grease to prevent corrosion, and but the bolt back in.

You can also try using an inline noise filter comming from your hot source. From the sounds of it, you have an FM-modulated cd changer, right? At the low MHz levels those things use, it is almost inevitable that you will pick up some noise from the alt, especially on lower-end changers (audiovox, dual, etc..)

You should check all of your grounds to check and for the exposed get some rubber sleves from an electronics store that you can shrink with a hair drier to insulate it and seal the exposed wire

I definately think it'* a bad ground somewhere, and if I forgot to mention, I took out the cd changer (which was fm modulated) cause of the problem, hoping it would fix it, but it did not. So I will try the grounds when I have a chance. Thanks guys

Anything else?

to no avail, I put an in-line filter on the 12 volt constant, and the noise is still there ... sob ... I checked all the wires in the back of the cassette player and they seem fine. I'm going to go to radio shack today and get some rubber sleeves in hopes that helps the situation. I talked to the guy at advanced to get his recommendations and he said to use the in-line filter and (I am replacing my alt with a 140 amp alt) replacing the alt will definately do the trick. and he'* 0 for 1 right now ... What grounds should I check? The only think I touched while putting in the cd changer was my truck, a wire going over the place, behind the passenger seats, under the moulding on the floor, under the carpet to the radio. Nothing else. The guy at advanced seem to say that it had something to do with the amp since only the back two speakers have the noise. Can I disconnect the amp and see if thats the problem?

So if any of you are going to advanced to replace your alt call them first and see if they have it in stock. My advanced had to order it and it takes 2 days to get here. Had I known that I would have ordered it a few days ago as I'm leaving tomorrow for school and wouldn't have time to replace the alt and make sure it was working properly before going back to school .... a little warning. Also he said that any bonneville with a heated windshield should have the 140 amp alt because of the power draw, and was surprised that GM put a 105 amp alt in our cars

Also, as a side note, one older advanced guy was being a douche. The 93 SSE came up supercharged and I told the guy I didn't have a supercharged engine. He said "well, then it'* an se" and I said, "no, it'* an sse, you can look at it *points outside*" So he calls to the older guy and he was arguing with me that an SSE is supercharged and thats that. I told him, "no, an ssei is supercharged, not an sse" and he just shook his head and walked off. I wanted to jump over the counter and smack some customer service into him, but I had other things to do
