Status changed: Good → Broken
The following is a list of dead lights.
The attached image shows the locations.
I could not determine which light is the “Right Lane Gumball” (#8).
None were replaced, however; beneath the Playfield each has been marked with blue tape.
- 2 Million (bottom left)
- Door Handle (mid field)
- 5 Million (lower leftside)
- Super Slot (mid field)
- Special (bottom right)
- 5 Million (Mid Field)
- Multiball (Upper Field)
- Gumball? (Lamp 86)
NOTE: It was determined that the black plastic bulb housing may have two “nubs” of plastic that are preventing it from fully being locked into place. This needs a closer inspection.
(Sorry no image available)
Got LED transmitter board working. To do: put capacitor on receiver board.
Details:
- All transmitter LEDs except #1 and #6 were failing or (in the case of the one Caleb removed) missing. I’m not sure if anyone had messed with LEDS 2,3,5 or 7, because several of these had been working just a couple weeks ago.
- Tested all resistors, all are perfect.
- Replaced LED #1 (the working but nonstandard one) + the missing LED #4, + all failing LEDs with original WPC-95 original specification LEDs. All are now transmitting well, see phone camera pics.
Note: our “PocketPD” DC power supply appears to be broken. At William’s suggestion I dug the extra fused bridge rectifier out of our “pinball electronics” box, and ran it to the right voltages using the big orange variac (see pics). This let me test emissions without having to be hooked up to the machine.
Removing back glass, the bulb looked grim. I replaced it. That made things better but not right, so I replaced the starter. That fixed it. It was the last spare starter, so I’ll order more.
Center ramp sensor was discombobulated and had trapped the ball. I put it back together and all is well.
Techs: Oliver & Drew
Problem: Right In-lane switch not detecting
Prediction: Bad Switch
Actions: Oliver and I tested & confirmed: switch is bad. Trimed leaf to length and replaced switch
Result: Right In-Lane switch detection
Conclusion: Problem Resolved
Problem: trough switch was not detecting ball.
“Locating Balls, Please Wait”
Observation: The white/green wire along the matrix was loose at one of the terminals causing erratic detection.
Action: Resoldered the wires to the terminal
Result: Right trough switch detects the ball
Conclusion: Problem Resolved
Flippers were kinda floppy, so I replaced the flipper linkages, which were worn. Regapped the right EOS switch so it opened later, making that flipper stronger. Used fancy new alignment tool to angle flippers properly.
Chime unit grommets were incredibly decayed. Replaced them. Sound is better, and they should no longer shake themselves apart. But we should also try adding the grommet spacers.
