Quoted from pinhead52:There is a db relay that pulls in when reset complete. there are contacts on this relay to reset each reel. the 10's digit contact is gaped too close in the tripped state BL-YEL RED-GR contacts on DB gaped too close
It's GR-RED (instead of RED-GR).
If the 10's reel resets whenever the score motor runs, then yeah, this DB switch.
