The startup relay was slightly out of alignment. A video shows correct operation.

Closed Problem: Startup sequence is looping
Work

Did some diagnosing and noticed a number of loose wires and bent leaf switches unable to be actuated. Our current assumption is that the four gears under the play field are trying to cycle to all zeroes on startup. The gears are sometimes too rigid to turn and the contact points that cause the next gears to rollover are likely not clean and getting actuated. Since the machine can’t recognize all the wheels are set to zero, it triggers and cycles everything until it reaches the default (inaccessible) state

Closed Problem: Startup sequence is looping
Work

Machine was not starting up. Button worked, but S relay wasn’t triggering. Sanded blades and adjusted alignment

Work
  • Found the missing screw. It had bounced over to the wall/floor line and gotten wedged there.
  • Fixed the 10k score stepper. It just needed some cleaning and everything started moving smoothly again.
  • There was also a solder point that was broken; removing the 10k stepper made that easy to get to, so I fixed it too.
  • Overall, it seems like it works now. Time to put it back where it belongs.
Work
  • This one has to be close. What’s remaining?
  • Fixed the 1 and 2 targets.
  • The pinballs look kinda rough! didn’t I replace them? Let’s definitely replace these.
Work
  • The wood on the board inside the backbox splintered.
    - I think it happened when I shook the machine a bit while playing, causing the board to come loose, swing on its hinge, and then stop suddenly at the bottom.
    - I ran over to Home Depot to get some glue and clamps and glued it up. I’m supposed to wait 24 hours to try it out, but I’m going to cheat a little and see if I can get it running again.
Work
  • It seems to be playing decently, but:
    - TODO check and replace bulbs
    - TODO is the 10k startup sequence right?
    - When starting up, the 10k reset behaves oddly, going through more positions than necessary. Is that right?
    - Took me a while to remember that the start solenoid doesn’t trigger any switches, so it looks different on the diagram
    - It seems to rotate through the zero positions, but never the nearest one
    - There are 3 zero positions. Let’s call them A, B, and C, which are at the 11, 3, and 7 o-clock spots.
    - I did a few trials. Starting at 0A, it went to 0C 4/4. Starting at 0B, it went 2/4 to 0A and 2/4 to 0C. Starting at OC it went to 0A 1/2 and 0B 1/2.
    - I notice that it sticks some. Hitting the 50k bumper causes 5 triggers, but doesn’t always advance 5. It seems to be sticker around 12 oclock.
    - This stickyness could account for the erratic behavior, so let’s fix that.
    - TODO clean and lube the 10k stepper.
    - TODO number 4 horse doesn’t always light the place position
    - TODO bend the horse targets
    - TODO clean and wax the playfield before closing up
    - TODO millions light alignment
    - TODO special light and special work?
    - TODO number 1 horse is sticky on return

  • It gets caught in the startup sequence. So what do I see?
    - I press the replay button.
    - That energizes the Start coil, which changes the state on the Start/S relay pair
    - That starts the score motor running
    - It resets the horse sequence units with a switch on Motor 2D
    - It loops on this forever
  • If I force trip the S relay, then it
    - resets the scores
    - energizes the ball release coil
    - that stays energized until I hit something that generates points
    - from here the game plays as normal
  • Also involved is the Z or Reset relay. That is triggered by the “minus 1” position on the 100,000 stepper. So I guess something kicks the reset solenoid on that?
  • So what’s the whole sequence?
    - replay button
    - start coil, flipping S switches
    - disables the start button
    - enables the score motor?
    - both
    - enables subtracting a replay
    - resets the 100,000 to minus 1
    - the 100,000 minus 1 switch triggers the Z/Reset relay, which
    - triggers the ball release
    - starts the score motor
    - enables the flipping back of the S relay when the score motor hits 4C
    - subtracts a replay at 1C
    - activates the horse resets
    - triggers the T and Counter relays
  • When I started this debugging, I knew one of the switch stacks was bent way out of true. But I discounted it as probably irrelevant, because I thought it had to have been that way before. However, bending it back and fixing the switch alignment fixed the problem. I did adjust some wire positions, so maybe there was a compensating short?
  • The machine is now back to being playable. There are a number of small things, one of which is that the backbox lights are a little off because the wood has worn or has bits missing. I used some putty to hopefully fix it.

  • It is looping on start. I’m pretty sure this behavior started before the move.
  • We found a broken solder connection on one of the race position solenoids. But fixing that didn’t help.
  • lOne of the score motor switch brackets is wildly bent. I can’t imagine that happening during the move, but I don’t know what it could be. I may want to ask Matt.
