I assume you mean one of the steppers in the back box when you say 10k motor. Probably you have a stuck playfield switch.

Quoted from BamBam1000:But when I return the Jones plug to its Socket I’m back to square one with the 10k coil going crazy and making horrible sounds
Quoted from HowardR:What is the 10,000 relay (N) doing when this happens?
Quoted from BamBam1000:I suspect you are asking what the 10k is doing with the jones plug out ?
World Champ has a 10k stepper and and a 10k relay. What is the 10k relay doing when the 10k stepper is "going crazy"?
Quoted from BamBam1000:Also did you receive my mail ?
Yes, thanks.
Reply from OP @bambam1000:
So I suspect the 10 000 relay is the N relay on the schematics
With the jones plug in it locks in and subsequently the 10 000 motor and coil go crazy
With the jones plug out the N relay is dormant
And I have checked the N relays ohms reading and it seems close to the original Spec

Quoted from BamBam1000:it locks in
If you can't see which one(s) of these indicated switches is causing that, put slips of paper in the them to isolate the cause.
