Thanks Gav, I'm currently at Rainbow Bay until 13th Sept. I'll be sticking my head back in 'The king' then, and will re-examine the 0-9 unit and motor switches at that time ... the electrical side of things has never been my strong suit when it comes to pinnie restoration. Thanks for your help here and i'm sure I'll be asking further questions about this mother of a machine... the first 4 player I've ever done in 21 years of restoring pinballs!  ... (I think I've done maybe 25 gottlieb wedgeheads by now) Cheers, Mark
