Hello all. I am an F-Body guy (84 Trans Am) . I have been repairing and modifying delco radios for the past few years. I have done some work for a few Fiero guys recently so I thought I would put a post here.

I have lots of used and NOS parts on hand to repair radios from the Early 80's up to the 2000's. I also do Aux Jack mods. If any one is looking for parts, repair, mods, or DIY mod info, please E-Mail or PM me.

Thanks 84 TA! I am 82 TA... hahah... I also used to be on ThirdGen.ORG when I owned my 1982 TransAm (miss that car).

Anyway, I'm definitely going to be interested in the next 6 months when I move back into my house and take my car out of storage. I'll save your e-mail address and hit you up.


Thanks!

Everyone, Thanks for making me feel welcome.

I have amassed a large amount of parts and used radios. They do me no good siting on a self. I started out repairing the radio for my Firebird and it became a hobby. I prefer the look of a stock radio, so I started fixing them for others.

The older delco radios that came in the Fieros are good quality they just happen to suffer from a few bad flaws. Most notably is the issue of failed capacitors. I'm sure some of you have experienced this. It usually starts with a bad/static right channel. If not repaired it can cause the audio IC to fail. On occasion the audio IC's will fail due to heat, or if someone has tried to bridge the channels together. In doing this repair many times for others I started getting requests to add aux jacks. Another issue I have see a few times is the clock will stay on and drain the battery of the car. This is attributed to a bad transistor. Again an easy fix. I hate to think about how many of these radios have been thrown away do to problems that are easily fixable.

Because many of these radios have failed, people have opted for the newer style radios (7 eq Pontiac radios, and CDM radios from the mid to late 90's) for their stock appearance. These to can be easily modified for the aux jack, and do not suffer from any problems expect for the volume pot to sometimes go bad.

Although I do offer repair work and mods, I am not here to solicit my services. I have many parts, radios, and information that I'm sure other DIYers are looking for.

Welcome to the Fiero forum. Do you repair Pontiac tube vintage radios from the 60's? I have a Delco "Wonder-Bar" with schematics that no longer plays. Tubes are good.

By the way your only 24 miles from my location and I use to have an 85 Trans Am.

I have no experience with the wonder bars. I would bet that its dried up paper caps and possibly a bad vibrator.

Perfect timing. I was just going to attempt to add an input to my 7 band Pontiac CD radio. Found a thread at a Bonneville forum (Adding line in to 86-99 Delco radios)) that showed the pinout of the RF module. That seemed to be the cleanest way to do to me. No need to put in a CD. Do his instructions seem right (I wouldn't use a relay, just a 5 wire jack that cut the input from the RF module).

Might try fixing one of my original radios too, I have three. Just to have the right radio for the car. Got any pics of what cap goes?

Thanks,
Tim

That is not the way I do it. The first picture that shows the connections close together on the bottom of the board is not correct. The second image that shows the connections on the longer traces that are highlighted in blue and red might work. I do all of my connections on the top side.

I am out of town for work right now, and do not have access to any pictures to show you where to make the connections. When I get back home I will send you pictures of the way I wire the jack.

Interesting. No rush, winter project, couple of months before I'll drive it again. Still need to pull it out and open it up. Tough to find much info about doing it at the radio input.

I think at least for now I will be staying with the stock look. What 1.5 din radios are we limited to? Some I have view have theft lock and can be lock picked I would think but I don't think they would still be functional, correct?

I found this writeup and bad capacitors in the radios like the Fieros:

Delco Radio repair

Popped open my original radio, looks just like it. One of the three caps he mentions even has some yellow goo on top.

Are these the ones you've found to be bad?

(Gotta get the snow off the Fiero bring it in the garage (yes no space for it all the time right now) and pull the CD radio out.)

Yes those are the first ones to fail. They are the filter caps for the right channel. The 100uF 16V axial caps will also go bad sometimes.
