How to Modify the Stock Fiero Radio for MP3 Players, With Pics. (Page 5/7)

I wasnt able to find an audio ground on the amp board, so I don't even know that it has one.

I really don't know how you could have killed it, outside of some sort of short when plugging/unplugging it. I never had that problem with all my testing though.

If you feel like mailing off your modified radio, I'd try to figure out what went wrong and how to fix it, so that it doesnt happen to anyone else. I'd hate to be responsable for killing off a bunch of Fiero radios.

OK, in the interest of making this work as I think it's a great adaptation for MP3 players I will send you my radio to see if you can figure out where I goofed up.

PM me your address and how much you neeed for the work, I'll let you know when I've shipped it out.

Here's a diagram and write-up I found on the web, a while back.
I haven't tried it, though.

Jax184, just to clarify, the MP3 signal should be going into the Amp board or into the two wires removed from the Amp board.

Into the amp board.

OK, did that right.

Only you can prevent fired fuses.

When plugging in or unplugging the IPod plug, I think the power switch for the radio should be in the off position to prevent elecrical spikes in the amp circuit.

*bump* to see if this was ever figured out?

Nope, sorry.

I've been so busy with other things I haven't been able to send my radio to Jax184, maybe this winter?

And I'm in the Sort-18-years-worth-of-stuff stage of moving, so I'm a little tied up as well.

A note though:
I had absolutly no problems with this method on my '84 AM/FM/tape non-equilizer model. It may just be something different about the EQ model.
