I'm finally working on the SF I got a long time ago.
I am no champion in EM, and I have the utmost difficulties to read the schematics, even though I watched several videos on it...
I do understand the basics though, and I am quite proficient on SS and modern machines.
So, I solved various issues, but am now stuck.
When starting a game, the score reels are reset, a credit is taken, and then it starts all over again, motor and reel are continuously turning, main relay assy is reset, and back to square 1. It'll go on doing this until I take the plug out, even though credits have been depleted in the meantime.
So from what I understand it looks like a contact staying closed, but I could not find it.
