CD100C Carousel problems

[tman]

Hi all. My cousin has a CD100C which now the carousel wont turn and get error 05-51/52/53 etc depending on where i manually move the gripper mech to touch the cam switches.

My cousin bought the machine with no display working and error lights on CCC that happened when previous owner tried to get cd working but swapped P1-P4 while the power was stil on. I ended up putting a new upgraded power supply circuit board in it as the 8v was only 6.25 and rowes upgrade kit show that it should of had the upgrade board in it but didn't and that fixed the display problem (even though a mobile repairer said the power supply is ok at 6.25v and said he needed another decoder board which was from a cdm4 and not the cdm12 which it has even though it has a cdm12 in it).

Does anyone have any ideas or would a bad cdm12 player stop the carousel from rotating as the voltages to the mech decoder are good now,

Thanks

Hi Travis,
What happens when you put the service switch in "service" and press the "cancel button" on the mechanism ? Watch the LEDs on the MCU--- Has the gripper returned and stopped at the correct "home" position ? CDM should not have any bearing on basket.

Hi Ron.  I did change my location (just found out I had to put it in status) after I posted as per rules which I forgot to do until after I posted,  if I have missed something please let me know.

When the machine is in service mode the cancel button does nothing.  There is power to the cancel switch and to the cam switches.  When powered on the mech decoder does the normal 3 flash board error, 1 flash cdm then rowe link flashes constantly until eventually after a minute of the carousel doing nothing, no gripper arm movement, no sprag solenoid unlocking the carousel, no carousel movement, after a minute it goes to board error as I assume because nothing is moving it is getting no response to the CCC so it all just resets and does the same thing 5 times until out of order comes up.

After i installed the power board upgrade and had no carousel rotation etc. I decided to open up and recheck the power board connections.  After putting it back in when I turned it on the carousel had started to go around and would not stop and cancel did nothing etc.  But the 9vdc light had gone off on the title rack module so I rechecked again and it didn't turn. I played with doing that a few times and once the locking mechanism to allow the carousel to turn would unlock and when I went to put the multi meter on the power supply pins out of curiosity  the solenoid stopped and the 9vdc light came back on as the connection might not of been so good and putting the meter into back of pins I guess pushed them on properly.  So maybe even with the updated power board there could be some fault there but would assume the voltage would drop at the mech board if it wasn't working properly.  Thanks

Travis,
Thanks---
Did you read the "sticky" at the top of this section--"common--problems"-- ? I assume you phono has some of these ! Ron Rich

Hi Ron.

I had cleaned and reset the connectors but I will do it again as maybe I didn't do a good enough job and they are not tight enough.  I also might buy some new connectors and terminals and run new power and earth leads to the mech and see what happens.  Thanks

Travis,
On the power supply internal plug from the transformer to the board--is there black wire (did you clean up this plug ?
On the wire going to the MCC, is there a "splice" on the black/white wire going to the power plug ( about 6-8 inches from the plug) ?
Check the power supply plug going to the CCU-- The plug from the PS MUST be the top plug in that series of plugs--also, what is the part # of the CCU, and which chip rev is installed ? Did you re-boot the CCU--is the battery good ?? Ron Rich

Hi Ron.

The power board I installed it in was a 61086501 which in the instructions has you remove the black wire.  Is it ok to extend the black wire and reconnect it as I assume it might earth a little better with it?

There was no black/wire splice 6-8" from the plug.  I did look for this wire but I cannot recall for what reason I looked for it now.  Is the missing amp reference wire next to the 28vac yellow wire ever used as it seems to not be there on the pics I have seen of other units.

I will try and get my cousin to see if the power input is in P1 or I will have to check when I visit again.

The CCC is a 40832225 with ver 3.9 and the mech board is a 61086201 with ver 5.5.  

I also have done the factory default reset, and it had a new battery holder and battery put in recently.

I will go there later in the week and try a few things and I was looking at buying some 3-770476-1 TE connectors as I think they fit in the plugs which would give a better contact on the pins.

Thanks

Travis,
NO--remove it --toss it out--It should not be used with ANY, PS board ! as for the yellow wire - I don't recall it --As for the CCC # ?? It should have either an 01, or 20, as the last two digits on that board. Ron Rich

Hi Ron.

The CCC is 40832225, it is actually on a sticker and not printed so I don't know what may be underneath the sticker if anything, but I have seen others with that number with a google search.   I will recheck the connections again and run some new wires for the mech earth and power when I go visit him next week and hopefully I will have some luck.    Thanks again

Hi Travis,
You are correct-- It's a later version of the "20". I have no idea what the difference is, as I never have seen one--(Rowe part numbers are the center 5 in the total number --the first two, indicate the {Rowe warehouse} location, and the last two indicate the revision number). Ron Rich

Hi Travis,
Prior to running new wires-- jump ( connect them "outboard", of the pins) the two grounds (earths)( black and black/white wires) at both the plug that goes to the edge connector on the power supply board, and at the plug on the CCC. These phono's had real problems with "ground loops" !

Hi Ron.

I will do that.  I did order some connectors and terminals to make a piggy back loom, but sticking the wires in the back will be quicker.   Thanks

Travis,
Do not use a double loom ! IF you replace the wires--you must follow the exact same route--and you should use larger diameter wires --

Hi Ron

No problems.  I thought it wouldn't of mattered as would be in parallel and that instead of jumping from the back of the plugs I would make short loom extensions using original type plugs and run the temporary test wires from the extension piece loom to get a better connection than poking wires in the back of plug sockets, and then if it that worked I would replace the wires in the original loom.

Thanks
