CD stacker help??

[wrx884]

Was coming home from work 2day i tried switching over 2 the cd stacker on the cd player but it wouldnt even reckonise that the stacker was installed. got home and tried 2 eject the cds, nothing, so it seems theres no power nemore? i checked all the plugs n leads all plugged in ok is there ne other way i can test 2 see if theres power gettin 2 it? or could it have just packed it in?

Its a Pioneer CDX-P670 6 disc stacker ne1 had ne probs with these b4?

The pioneer stacker has a constant power wire going to it. Its the white plug next to the pioneer p-bus stacker lead at the back of the stacker. This plug also has a ground wire. Check to see if power is there. If power and ground is present on both these wires try checking the p-bus lead to make sure it has not been squashed. Then disconnect battery for 30 seconds and reconnect, sometimes devices can freeze until power is removed and reconnected. Also make sure all leads are firmly plugged in. If all these don't get the stacker working it is most likely it is faulty.

no worries i'll give it a go yer 1st time its played up, is a few years old so thought mayb it was on its way out but i'll check these out 1st thanx

ne other suggestions im all ears?

The stacker will eject with only power connected, no IP-BUS lead so it's not a IP_BUS failure. As said, check for power at the plug. If there is power there, there is problem with the stacker.

I've seen those have dry solder joints of the power connector on the power supply board and the 2 ribbon cables inside can go resistive between tracks. So if you really want, you could order the two ribbon cables and give it a go yourself or send it to Pioneer.

ok just checked 4 power and theres nothing in the lead i tried finding another grounding point but no luck. havent pulled the seat out yet as the stackers under there mite have 2 wait till the weekend 2 do but wen it was installed i made sure the wire wasnt squashed by nething but will still check just incase.

was thinkin tho does the power lead always have consistant power? coz if its not then the only time it will have power is wen its selected on the cd player is there a way round that if thats the case? or can u test the lead itself with out gettin a new 1 4 the moment incase its that thats faulty?

The stacker power lead always has power. Should have a constant 12v line and a ground line.

hate to state the obvious but did u check the inline fuse on the power for the stacker?

[wrx884]

I think u might b on the money stevieP i searched 4 my manual 2 see if there was and where bout the inline fuse was, i also read there was a reset button on the stacker i tried that still didnt work so i tried tracing the wire lookin 4 the inline fuse as i wasnt sure where bouts on the lead it was as i got under neith the glove and behind the carpet i touched the wire n it started 2 work :S still couldnt see the inline fuse or feel it but i think i'll have 2 pull the CD player and dash out 2 see if its behind there. Its weird coz i was playin with that cord in the same place yesterday wen i had a breif look ay

Do u think from touchin the wires the fuse might have been loose or on its way out? i'll have a good look on the weekend n check it out coz im not even sure the fuse is behind the cd player yet.

how are you checking for power, are you using a test light multimeter, etc. i have had pioneer stackers that have had power on the white plug an sent of to repair, then come back with no fault found, then changed p bus lead and stacker worked fine. So yes it can still be a p bus failure. when i install stackers like this i remove the in line fuse and wire to the same constant as the head unit. so in the event of fault, changing a fuse in the fuse panel of a car is much easier than removing a head unit.

yer tested it with a voltage meter that has a test light in it i checked it wen it started workin again and it showed power in the lead so i duno i just think mayb stevieP is right but wont know till i pull it out. so how can ya test if its the P bus failing? best 2 get a new 1 n see if it does it?

[Luke0011]

yer tested it with a voltage meter that has a test light in it i checked it wen it started workin again and it showed power in the lead.

If stevieP is right then why are you saying it has power, why would you check the fuse if you know there is power there. if you disconnect the p-bus lead and you know there is power there, and the magazine does not eject then the stacker is faulty, send it off for repair at a car audio shop and they will charge about 30 dollars just to tell you whats wrong. SO MAKE SURE there is power and ground at the white plug. good luck

coz as i said earlier there was no power even wen i tested it the 1st time it wasnt till i touched the wire 2day under the glove box part it got power again and its still doin it now went 2 move my car and there was no power again

[StoneX]

Rewire the stacker's power cable then, there must be a break or poor contact somewhere.

[Phreddy]

Hey Guys.

Sometimes those cheap inline 3AG fuse holders will break the contact to the fuse if there's any tension on the wire. Because it's only that spring inside the housing that push the contacts to the ends of the fuse, if the wire is stretched it can pull this spring back, and bingo. Air gap in your fuse holder.

Worth a look Ant. Cheerz!

EDIT: That's if it IS actually a 3AG fuse in one of them holders...

thanx greg will have a look 2moz after work noticed 2day i got it goin on my way home from work by fiddling with that same wire in the same place again i assume the fuse aint far away from it neways it was cuttin in n out a few times this time so looks like i may have 2 pull it all out n go over the lot will let ya know if i find somthing
