GTB 1978 Neptune:
Everything works except the Red Cards WOW when all red cards (9 10 J Q K A) are hit. Black cards work fine. I have the schematic and traced the possible issue on the schematic to the R1-R6 switches. All of them need to be closed for the Sequence Complete relay to fire.
I cleaned the contacts and checked the gaps on R1-R6 and all seem good. The KS and AS steppers are working fine. The Black Sequence Complete relay works fine, but the Red Sequence Complete relay isn’t getting power even after hitting all red cards. Is there another pathway to activate the Red Sequence Complete relay?
Thanks, Steve.
