fixing am radio?

From what I remember It did not do anything but last time i checked was when i took it out 2 or 3 years ago. Its a motorola, do you think i can find any schematics if i search around?

Honestly I don't have much electronics experience. I can hook up a radio but don't know anything about the internal workings (yet).

I did put together a megasquirt computer last winter but they pretty much told you where to put everything.

I'm not asking you to spoon feed me, just give me some tips and places to go that might be helpful and ill be grateful.
