Working on getting my Hay Ride working 100% after an amazing playfield restoration. I've already mentioned the issues I'm having with the free ball gate in another thread. The other problem I'm having is with the ball in play and game over lights.

When a ball is discharged into the shooter lane, and when points are scored, the ball in play lights flash briefly, then go out again. The game over light flashes briefly at the end of the game. Obviously, these are supposed to remain lit.

I've poked and prodded everything I can think of. The ball in play stepper itself is clean and works otherwise flawlessly. GI and playfield insert lights work flawlessly. What I think is the relevant portion of the schematic is below...

To add- that game over trip relay is spotlessly clean and has continuity. Besides, if that were the problem, the lights wouldn't even flicker, right?

You sir, are a gentleman and a scholar! I was testing the switch at the relay, and it had continuity, so I assumed all was well. After seeing your message I started working my way backwards, and discovered that the 71-5 wire had a break in it. Patched in a bit of new wire, and those lights are now working.

Yup. That's the first thing I do with any EM, but it's especially important for Bally's. All six fuse holders were replaced before I even tried to turn the machine on.
