I have a 92 coupe with what I believe is an original jag radio, where the security light will flash but that is the only sign of life. I was told that means it is getting power but I do not know which wires to test or supply power to for testing. I do have a security code from the prior owner, but the radio had been removed from the car previously. Mis-matched screws holding it in.
Where would you begin? Assuming this is an original radio, with original wiring, what I should the troubleshooting process?
Thanks in advance.
