Re: Radio / electrical problem, need ideas.
I'm guessing here...There are three 12 volt inputs to the radio:
1. 12 volt supply to the AMPs.
2. 12 volt supply to the memory.
3. 12 volt supply for a powered antenna.
Now, the first question:
After the lights are turned on and everything returns to "normal" and you're toolin' down the highway... watch the display on the CD control head. If it's LED/LCD does it "Pulse" with the music... or does it gain or loose brightness as the low booming base notes sound?
Now a CD changer doesn't take a great deal of power.. but it IS sensitive to power fluctutations. When ever you pull on the lights the power does flucutate, and a short lowering of the source occurs as the regulator catches up. During this short pulse of lowered voltage the CD, though not brain dead (the memory still works) becomes unable to operate, spin or change CD's, etc..
I'd change the CD's power input (number 1 above) to another source. Were it mine, I'd install an auxilary fuse box off the batter and mount it in the engine compartment. I would wire the input to the fuse box directly from the battery and take the source voltage off one of the fused outputs.
