Whenever I push the power on button to the head unit or by turning on the car ignition key which in turn, turns on the head unit the cd shuttle will eject. With the cd shuttle pushed back in and the car running it will regulrarly eject itself again after about 3 minutes.
With the car engine off, the head unit on and then pushing the cd shuttle back in it will play cd's fine.
With the head unit unplugged and the cd shuttle plugged in I can turn the cars engine on and off fine without the shuttle ejecting.
This is a recent problem and had all been going fine for anumber of years.
Though I'm not sure it could well of come about with the cd player on when the cars battery was disconnected.
Any help appreciated.
Adam.
Hi Adam,
Since you've been trying things for so long, you may not mind another, unless you've tried it already.You'll need someone to help you.
Try using a volt meter on the main power to the changer. (If the changer is din mowered only, this can't be done) and when toy power up the head unit by ignition or other method, read the voltage on the main power wire (yellow?). Tell me what it shows. Also, the "turn on" wire for the unit is usully in with the data cable to the unit, and won't be able to check that.
Also try to read BOTH the acc AND the power wire on the head unit while turning on.
When you read the voltges, make sure that you use the ground ON THE CHASSIS of the componant that you are checking. "Maybe" you have a voltage variance like you said d to a weak ground at one of the units? I'm just troubleshooting as I would if you had brought it to me. Let me know again. Thanks.
** Note- Have you actually reset bothe the head unit and changer?

Hi Larry
I have spent the last week trying different scenarios out on when I shuttle ejects. For the majority of the time it happens when the power to the head unit is turned on or the cars ignition key is turned. After pushing the CD shuttle back in it will play fine.
It was suggested to me when the head unit turns on it goes over +12v reset threshold and that if the stereo is designed to treat a loaded CD on master reset as an error, it would likely eject.
Since the problem occurred which was a good nine months ago I have had the alternator tested and have put in a new car battery.
I think it is unlikely to be a fault with the way the unit is wired to the car. I have done it to the way the manual says to and the CD player had been working well for a number of years prior. I have checked for loose wires.
I hope this helps more for a solution.

In my 29 years in the industry I can honestly say I have NEVER seen that!! Can yu tell me how it's wired? I know how it SHOUD e wired. Hit me bac.
