Check the RCA connector where it plugs into the circuit board. Sometimes the wires get broken, especially the shield to the outer shell. Sometimes you can lightly squeeze the shell to make better connection to the socket. When the record is returned to the rack, there is no solenoid or relay activated. Only control switches on the front of the mech open or close depending on their function.  On Thursday, May 23, 2024 at 03:14:13 PM EDT, Glenis&Rod via Jukebox-list jukebox-list@lists.netlojix.com wrote:

Hello,

I have a Seeburg KD200 which has been working for 10 years.

However, now after making a selection it now plays all records sequentially starting at the position of the mechanism ignoring the selection.

I have a Service Manual which describes in detail settling and adjustments.

In order to trace this fault a 'Control Sequence Diagram' would be very useful.

I have seen Control Sequence Diagrams for later Seeburg JBs - semiconductor models which gives some information.

I have inquired on other forums without reply.

Any diagnostic information will be appreciated.

Can anyone please tell me "what is the signal or relay/solenoid that is activated when a record has been returned to the rack"?

Rod
