Hi Folks, I played about 6 records on the AMI Continental today and once the final selection had been returned to the record basket, it would not switch off and continued to rotate until I switched the machine off. I switched it back on, but carousel was still rotating. I am still able to make selections as before. Before I start looking into it, perhaps someone could point me in the right direction. I have not encountered this problem before, but would I be correct in thinking this is something to do with the stopping switches? I am going to dig my manual out and try and figure out what is going on. Any help and advice would be appreciated. Thanks Gary

Hi Gary,
My great, but not too long memory has totally failed me on what makes a Conti basket turn-- I'm thinking that there is a "scan control assembly" in it ? If correct, this would indicate that it is failing to subtract motor run time. I THINK. this is controlled by a rubber wheel, that tends to get "slippery"-- I doubt the "stopping switches" have any duties here ? Ron Rich

Hi Ron, thanks for that. I guess I meant to say stop/start switch rather than stopping switches which are located on the rear of the carousel. Under normal operation, once the last selection has played and the record returned to the basket, the carousel would rotate about one complete revolution before switching itself off. Just need to find out why this is not happening any more. I will try and get the cover off tomorrow and see if there is anything obvious that has happened. I will report back with my findings. Thanks Gary

Hi Gary,
That's what my memory is telling me--It now says that the scan control assembly rubber has hardened-- Last time I checked, it was still available at one, or more of the suppliers, listed in our FAQ's section. Ron Rich

There's a scan control unit, it's belt driven from the shaft of the magazine motor that drives the popularity counter. You'll definitely find the details in the manual.

Hi Norman,
My remember-or, says it's a friction drive, of some type-- correct , or not ?

It's belt driven. There's a spring loaded gearwheel that operates a limit switch - when a selection is made, a solenoid releases this gearwheel to make the switch. A smaller wheel with a notch is driven by the belt from the main carousel shaft for the popularity counter. This second wheel engages with the gearwheel winding it and the spring up until it opens the switch stopping the rotation. You end up getting just over a complete revolution of the carousel from its location when the last selection was made. That's as brief a description as I can manage!
The belt will probably be slipping or maybe the whole thing is a bit gummed up.
Norman.

Hi Ron, Norman and anyone else who has been following this thread. Just to let you know that the problem has now been fixed but will continue to monitor the situation. Apologies in advance for my non tech description, but hopefully you will get the gist of my findings. Once the deck cover was removed, I could see that the rubber drive belt was turning on the top nylon cog, but not turning the cog itself. As far as I can make out the cog should turn the ratchet which releases the spring which releases a lever which in turn switches the motor off (or something to that affect). The cog was dirty and pretty well seized up. So, cleaned it up, added a couple of drops of light weight machine oil on the shaft and all seems fine now. Just as a matter of interest, if anyone has ever replaced that belt, it would be good to know how they did it, because it looks like it would be quite a task to get it out. Hopefully I won't have to do it. Thanks Gary

There's a rubber coupling on the shaft from the drive motor which can be undone to get the belt on.

Hi Norman. I can see the coupling, but just curious as to how you would access it. It looks like it would need to be a mechanism out task to replace the belt. Here's hoping the need won't arise. Maybe catch up with you next time I am up visiting my brother in Aberdeen. Obviously once all the pandemic stuff has been sorted. Regards Gary

Hi gary,
The manual shows the coupling on page RCS-2 clamped with two screws. There is an easy way to replace the belt - get some O-ring material of the right diameter, cut it to length, loop it over the drive shaft and then glue the two ends together!
Norman.
