Hello,
I bought a 1992 960 Wagon this spring, and it's already broken my heart ( it had the fabled porous engine block).
A few nights ago I attempted to install a CD changer in place of the radio. I assumed it would be a simple matter, but I was wrong.
Initially, the CD changer only worked when the headlights were off, and the instrument panel lights don't turn on. I then searched brickboard, and went back outside in the cold December night with a multimeter.
I think that I initially connected the power antenna output of the CD changer to the Illumination lead from the Volvo. I disconnected the antenna, and then verified that the ground was indeed the ground, the red was indeed the ignition power, and the black with yellow stripe was the battery.
I checked the fuse for the instrument lights (10 I believe) and it was fine.
At this point I'm thinking the Illumination lead is in series with the Instrument lighting. Am I wrong? What else can I check?
Thanks,
George
