I have a 1985 reliant se 2.2l with efi, I think the radio quit working, kept cutting on and off now quit working at all, display dosent light up. does it run off the battery or altenator? could it be a voltage issue or did the radios go bad?
Chrysler had some electronics suppliers (Mitsubishi in particular, I believe, but I'm not sure if they used them in '85) that manufactured products with "cold" solder joints in them, meaning the solder wasn't heated enough when the unit was manufactured, leading to flaky reliability down the road. IIRC, it's not all that uncommon in Huntsville decks, either. Fortunately, one of our members has made up some excellent tear down and repair guides for many common stereos, so if it comes to that, you can have some idea of what you're doing.
