If yyou have some real bad connections and you need to solve thisou have voltage drops when you open the door you got a short problem. there is no way that you should have no more than 1.5 volts of load on the system. even turning all the lights the heater stereo a/c and everything else would put that kind of load on your electrical system. i would deal with the electrical problem first. then go get another deck because chances are your input power module is no good in the deck. before replacing the deck in vehicle make sure you have no more than 1 volt of load drop in that circuit.
It think you should investigate this relay closer i am assuming this was installed at the dealer as an option?, my guess would be where they tapped into for power for the changer control under the dash is controlled by this relay for the interior light circuit(auto dimming), the memory circuit in the changer cannot operate on the 5v (dimmer control) and you are loosing your memory, i understand you don't want to take apart the dash but i have a feeling you will find your problem where they have jacked into for power under the dash.. i would locate that and remove it from this auto dimming circuit, and run another 12v constant feed to the changer sorry i cannot offer you a diagram but i think you will find the problem as you seem very determined and quite qualified please rate -jeff
Can you tell us if the radio is keeping station memory etc? and time? there is a chance your cd player is set up to always start from 1 (yes there are some out there). maybe the head unit seimens wont talk properly to the blaupunkt stacker? try a blaupunkt head unit? i would suggest running a new memory wire to the head unit. let us know how this helps
If you supply wrong voltages to CD changer you get a fault most of the times, not only not keeping memory.
The radio (not hthe changer, the stereo itself) has a memory input, I think it is +5V, If it had not been connected it will reset the CD memory also, check the back of the radio and find power for memory settings. If it is not connected or connector is bad, that is the problem.
" I have replaced the cd changer and the radio/cd and problem persists"
This is because the problem is not the CD changer, or the CD changer wiring. The problem it is in the radio wiring, the memory positive supply cable connection is not working, then radio lose memory of CD changer position. Tell me your radio model, I see if I have wiring for it, you must be quick as I am going offline, or ask to one of the others.

"There is a yellow wire on pin 7 which has got 12 volts with the car ignition off and the car door closed which goes down to 5 volt with the car door open, and restores to 12 volt a few seconds after the car door is closed - there is another orange wire on pin 7 which works exactly the opposite"
That is also a problem, That is a contact! each time this happens you reset the cd changer same as if you disconnect battery cable.
Remove door panel, or whatever you need to remove and fix the bad wiring first, otherwise is useless troubleshooting.
Check also your car stereo wiring on the manual and see if memory + cable is present, otherwise you reset the radio each time you restart the car.

One wire to remove, the original wire going to pin 9. In lieu of that, put a jumper wire from pin 9 to the white wire ensuring that the white wire is getting an always on B+12.
try local car mechanic instead of compant service technician.it would be quiet cheaper.and also not take so long to get it done.just you have to be him all the procedure that he does not damage or replace any part without letting you.the technician on site is vwry much necessary in your case.as the wiring diagram for your device is not available.

The voltage should always be constant through the red wire which is a 12/14 gauge in size. when you turn the key the voltage should flow to the deck to power it up. this should also be 12/14 gauge. this is the accessory circuit.. now i read that when you open your door opens that the voltage drops. which wire does the voltage drop from? the yellow or the red. this is important because if it drops from the circuit of the red wire you have a draw on the system form something that is unrelated to you stereo deck but enough that it draws too much voltage so that your memory cuts out.
ok if you have just yellow and orange wires the yellow is constant and the orange is the accessory. blaupunkt is a german manufacture and they don't always use the same wire codes we do in the states, however you should go and get a replacement harness that matches the factory connector of your vehicle to the stereo deck these are very specific the shunt that you have is faulty. if you have constant current with the car off and you have current with the key turned on and you lose memory it is not the vehicle circuit it is either the harness adapter or your stereo deck and if it is the deck then it is an internal and most likely the power supply module on the circuit board...........please rate this............thanksok if you have just yellow and orange wires the yellow is constant and the orange is the accessory. blaupunkt is a german manufacture and they don't always use the same wire codes we do in the states, however you should go and get a replacement harness that matches the factory connector of your vehicle to the stereo deck these are very specific the shunt that you have is faulty. if you have constant current with the car off and you have current with the key turned on and you lose memory it is not the vehicle circuit it is either the harness adapter or your stereo deck and if it is the deck then it is an internal and most likely the power supply module on the circuit board...........please rate this............thanks

Unplug its wiring harness connections, inspect, make sure contacts are ok, reconnect according manual instructions and try again. Make sure also loop play is not displayed.
The slider mechanism, depending on the age of the unit and the manufacturer, consists of the small chrome rail, a drive motor, a small gear assembly, and (in some units) a small belt that drives the slider unit via the motor. This small belt causes all sorts of problems. If the belt is broken or slipping, it can cause skipping, dropouts, or simply no start up at all. Also, if the belt breaks in the middle of the disc, the drive mechanism gets hair or dirt wrapped up into the gears, or the pick-up assembly doesn’t return to the start position (called home), the unit will (99% of the time) refuse to release the disc, causing it to become stuck inside the unit. There’s a little micro or leaf type switch located at home position that sometimes gets dirty or breaks and, causing this problem also. If the disc starts to spin slowly and doesn’t come up to speed, the spindle motor that’s attached to the turntable platter is a common problem. There could also be a problem with the spindle motor driver controller IC or the power supply regulator that supplies voltage to the driver IC. If the disc starts to spin and then spins really fast, or stops and starts to spin backwards, your problem is the laser pick-up assembly or the servo control circuit. If you continue to have problems after cleaning and checking the other things listed above, you may have a problem with the player's alignment. Of course, one of the problems you'll face checking alignments on a DVD/CD player is that you’re going to need to use an oscilloscope on most of them.
The yellow wire needs a constant 12 volts to maintain memory. It drops to 5 volts and thus causes a reset of the changer and that is why the memory is lost. Connect that wire directly to the battery. Then you may want to find out why that wire drops to 5 volts, it could be a problem in another part of the electrical system. It should not be dropping to 5 volts when you open the door. That is your problem. Once that wire is directly connected to the battery, your memory problem is solved, but you will have another problem somewhere else iin regards to the door opening and it drops to 5 volts.
The cd changer needs a full 12 volts to keep it's memory. If it drops below a certain threshold it will consider it as not being there and then when the voltage comes back it initializes as if it was just connected. As i stated before, if you run this wire that is dropping in voltage directly to the battery it should solve your memory loss problem. then you would need to find the problem with the door opening and causing it to drop the voltage. It could be a switch that is getting loaded down somehow, but it does seem to be the problem for you.

It could be few things but >1st try the fuse panel in your car the fuse for the radio memory could be blown or lose(check the car manual for the Location of the RADIO MEMORY FUSE) >The stereo buttons on the front can get stuck so if this is the problem and the REPEAT is stuck or shuffle ETC. JUST make sure to see if the buutons are all working.
Verify that the CD Changer is properly connected to the vehicles body harness. Double check the fuse relay. Turn the vehicles ignition switch to Accesssory.
NOTE: See owners manual of the CD Changer for more information on controlling the changers operations through the vehicles radio.
As in most memory circuitry, there needs to be a constant B+ supply. Pls check the connector terminals with a DVM. With no key in the ignition, at least one of those connectors/terminals/wire should have an always on +12. If none, then it would be required to doubleback the harness to its origin and determine which of the wires is disconnected.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.
Could you try on pin 9: make it "no connection" by removing the original wire from the harness; and/or removing the original wire from the harness and connecting it to thw white also.

The logic circuit that holds memory i.e. time and user setting has failed, the voltage it operates at is 10-18 volts, you will have to replace the head unit to correct this, Your local dealer can provide links to exchange the unit, then you just give them your old one and they provide you with a rebuilt unit, it's quick and easy.

When u hooked it up there should have been a yellow wire for the memory that runs with the hot wire so that the system will hold its memory
Sir,
sounds like your cd changer isn't hooked up to a constant 12 volts that is holding the memory. or your cd player isnt.
thanks
good luck
Can you look for another posibilities that may occur the problem. like your settings on the menu. it must be played repeatedly.

Thanks
The problem may be because the contsant 12V and the memory
12v need to be changed over, the wires should be the red and yellow, if
i remember rightly.
if you look at the plug face on, the yellow wire is top second on the right, and the red is second line down far right.
Please rate the solution.
