[Jukebox-list] Seeburg STD3 selection problem

Hi, I'm working on a Seeburg STD3 wiith a selection problem. All selections work using the battery trick but when I make a selection with the keyboard, any selection where the third digit is 9, I get 0. If I select 119, it scans and picks up 110. !29 I get 120 etc. I have the manual and Ron's microlog book. I think I read somewhere in one of the books that if it's a single selection, It's in the keyboard. Would anyone know what I would be looking at? I don't see a loose or broken wire. Thanks, Doug
