Quoted from WhiskeyPinball:I have tested the circuit with jumpers (one jumper on the red-white wire and one jumper furthest away, starting at the S relay Blue-white wire. S relay energizes up until the yellow wire on score motor 1C (this yellow wire goes from 1C outer switch to SB relay).
I would think the S relay would still energize since the yellow wire / SB relay is in the path unless I am thinking incorrectly?[quoted image]
You SHOULD have a path through the normally closed switch at 1C, but the fact that the S relay is not energizing when you move the jumper to the yellow wire there suggests that this NC contact needs to be checked.
Good luck!
