I had a problem with the Sony CD player on my car radio/cassette/CD player so I bought a complete new unit which I've just installed.
The only mistake I made was forgetting to remove one of my CDs from the old unit before removing it from the car. So now the CD is stuck inside the old unit and I somehow need to power the unit up so that I can eject the CD ! I have an old car battery I can use for this purpose.
I have the wiring diagram for the unit so I know which pins are the continuous power supply and switched power supply ( I assume that both of those are + ). I also know which pin is the earth.
Am I correct in guessing that I need to get positive on the switched power supply and negative (as the car is negative earth) on the earth to power up the unit ? ( Or do car radio/cassette/CD players usually get their negative supply via the casing's connection to the car body ? ) Excuse my ignorance ! .
Hope someone can advise me - Thanks in advance ! .
