Hi wesley
I read You have the problem "after starting a new game then the O-Ball-Return-Relay does not activate". See the JPG - question - when the fault happens / shows up: CAN You actuate the Flipper-Bats ? If "Yes" - wear rubber gloves, do NOT touch metal - use an wooden stick - manually actuate the O-Relay-Armature (You simulate: Relay pulls-in) - then let go the wooden stick - big question: Does the O-Relay keeps on pulling (for a while) - stays pulling ?
See the JPG - "my red line" is "wiring to make the O-Relay to pull-in" and "my blue line" is "wiring to keep pulling / stay pulling. Depending on Your answer (to Does the O-Relay keeps on pulling (for a while) - stays pulling ?) there is mor or less wiring / switches to check. Greetings Rolf
