No power at cd changer, cable continuity fine, need to trace back to power source. The cable runs from the cd changer to the radio and out of the radio the connectors on the fascia at the front. What rout does the cable take then to collect the 12 volts. When I turn the ignition key on the cd changer doesn't do a cd check like it use to. Please help

I will give you a full rundown on how to install the cd changer;
Disconnect the car battery.
Run the cable from the Jensen changer to the back of your dashboard. Depending where you mount the changer, you might want to hide the cable under the carpet or run it along the door panel. Take some time before you mount the changer to figure out what is the best way to run the cable for your situation.
Remove your deck and the dashboard around it to access the back of the deck.
Locate the antenna lead plugged in to the back of your deck. Unplug it.
Find a good space to mount the FM modulator behind the dash and close enough to the deck to connect the antenna lead. You can secure the modulator to the inside of your dash by using two sided Velcro tape and place it where you need. Plug the antenna lead into the modulator's "Antenna In."
Connect the FM modulator to your deck by plugging the "Antenna Out" lead off the modulator to the antenna in on your deck.
Connect the two power cables from the modulator to your car's power. One lead goes to a constant source of power and one connects to a switched 12-volt power source.
Ground the modulator by running the black wire to an exposed screw. Wrap the wire around the screw and tighten it down so the wire doesn't come loose.
Reinstall your deck and dashboard.
Find a spot on your dash to mount the display unit. You can get creative and cut a hole in your dash and mount it that way or you can use Velcro tape and place it on your dash that way. Make sure it is close enough to the driver's seat so it can be accessed without having to reach too far. If there are loose wires hanging from under the dash you will want to tuck them under the dash and wrap them with wire ties.
there should be a small connector on the changer itself for the power ground and remote wire for power to the changer unit. the cord coming from the unit to the changer doesn't supply this power and this is why it wont eject and also your head unit wont recognize it until it gets powered up and able to communicate with the head unit and then it will show up as a selectable source when switching between sources of music. check the back of the changer for a small connector containing 3 or 4 pins and you should have a connector with the corresponding wires coming from it to plug into this spot after connecting the wires properly. if you bought it on ebay it is possible you didn't get this piece which is critical when connecting this changer.
if i remember correctly there is an inline fuse for that unit (more than likely tucked behind the radio) check that first. if its not there, just trace the wire back (from the changer) to its power source and see if that is getting power, there might be a factory fuse blown... let me know what you find. As for a replacement controller, i would contact Jensen directly, most of the time they can sell you one for a reasonable price. Why makes you suspect the controller, does the unit seem like it is still functional?
Have you tried to replace the lamp? A good source of supply is at www.victoryglass.com
If the lamp is ok then trace out the cables that supply the lamp back to the jukebox power supply. It could be a dry joint (cold joint in the USA) on the connection pins on the board. It could also be a problem with the lampholder.
My wife's 2001 Jetta TDI had the same problem. First we changed the battery. (It was just about due anyway) No change. We then traced the power drain to the in-trunk mounted CD changer. This was an aftermarket CD changer but we went to the same source that the VW dealership uses. Of course one blames the other. The CD changer was even replaced with no change. If we are not using the car for long trips we unplug the CD changer and no more dead battery! Neither the VW dealer nor the AV installer could give us a good working solution to this problem.
i resolved this myself in the end. I unplugged the audio & power cables whilst the stereo and engine was running. Then plugged back in. I turned the engine off and stereo off as well. I then unplugged audio and power again from the back of the CDX, left it unplugged for 10 minutes whilst the engine was still off. I then plugged the leads back in and turned the engine on. the stereo recognised the CDX, but stayed on displaying "CD Checking". I switched to radio for 20 seconds, turned back to CDX and it selected CD 1 and has been good ever since.
i have the same exact problem with mine. what i did was manually pull open the cd deck, stop the disk carousel from spninning by holding it still, then push the deck closed. the cd deck will no longer work, but at least it stops spinning. the auxiliary works fine and so does the radio.
