And here is what I was greeted with when I lifted the playfield at home today. The 1st pic is the outhole switch.. theres no way that could’ve EVER worked!!! (I didn’t even bother lifting the PF for a look when I picked up the game).

Notice the two stepper unit pics, the bakelite switch PCBs on the two units mounted to the bottom of the PF are both damaged.. one must’ve worn out and was repaired with bits of thin metal soldered onto the PCB, and the other had the bottom section snapped off and completely missing ( I only discovered this one after switching the game on to see if anything worked). Seeing this my heart sank and I began to have thoughts that I might’ve wasted my money on this machine, but after thinking about it for a while I have a plan to repair these stepper units boards. *%*

Also notice the melted insulation on the yellow wires in the score motor switches in the last pic.

I’d decided first thing to do was to see what did and didn’t work. Initially not much happened, the score reels tried to reset, some did reset ok but a couple were sluggish so I just reset them by hand for the moment. Flippers, bumpers and slings all worked (good start), but none of the scoring relays would latch, I eventually found a switch in the score motor that completes the latch circuit for the relays and opens the circuit after points are scored (readjusted the switch). I’ve got heaps more to do yet.. outhole relay still not latching, scoring switches are activating the 100, 1k, 10k point relays but the reels are not advancing which is causing coils to lock on, because the latch circuit is not being broken EOS switch on the reels. (I worked this out by advancing the reels by hand, when the reel coil plunger is pushed in the score relays reset and the locked on coils release.

I’ll get there eventually!!!

There was no manual or schematic with this game so I’m flying blind with the repairs. I do have some of it working, I gave the seized stepper units a quick clean up (I’ll restore them properly later) and have adjusted a few switches. I’ll get it all working first before I do any cleaning repainting etc. I definitely have my work cut out for me with the electrical/mechanical repairs to this one!!
