Issue JD-20160312 multiple problems as delivered

  • Crane was not bolted in
    • Bolted in and aligned using set screw
  • Deadworld loose & misaligned
    • Fixed
  • Left flipper EOS switch non functional
    • found loose common earth wire under playfield and soldered it back on
  • Drop targets unable to be raised by coil
    • TEMPORARY fix: Locking clip lost so Opto PCB tilted and is getting hit by coil activate drop target lifting plate, just tilted PCB back to parallel
  • A few ramps etc loose here and there, tightened as each is found
  • Gets stuck with multiple balls in shooter lane
    • Filed divots from ball through
    • cleaned trough sender & receiver LEDs but still faulty
    • resoldered trough Opto sender PCB
    • still faulty so replaced sender LEDs & current limiting resistors  (Jaycar part ZD1945 works fine), reduced current slightly on feeling slightly more modern (hopefully) LEDs more efficient
    • adjusted shooter lane microswitch
    • tightened shooter coil & replaced sleeve (Did left side at same time
    • tightened trough coil & replaced sleeve
    • Trough issues resource: Http://www.pinballrebel.com/game/pins/ij2/shop/Trough.htm
  • Both flippers activated = resets
    • Replaced BR1/2 (GBPC3504W) C5/11
  • Both main flippers way too much shaft end play

Issues as delivered NOT yet resolved:

  • 1 GI strip out. A fuse is loose on power PCB, Wriggling fixed it for now (Resoldered during Issue JD-20180324)
  • Drop targets unable to be raised by coil: need permanent fix (Added missing circlip during Issue JD-20180324)

Other improvements

It had maybe 5% leds, replaced most of remaining GI & Controlled, as well as all flashers
Dirty playfield, gave it a cursory clean, pending a full future strip down
Cleaned those Opto pairs I could easily get to


Issue JD-20180320 Multiple issues – resolved

Observations:

  • On power up a solenoid somewhere fires a few times before going quiet
  • On game start launches multiple balls
  • On game start continuously launches balls
  • On game start flippers non responsive but work ok through Solenoid tests

Secondary observations after commencing investigation:

  • Opto trough transmitter board doesn’t have LED8 (Power indicator) on
    • IJ manual shows as supplied from unregulated +12V
  • On Power Driver Board
    • Led1 is indicator for +12V regulated supply & is on as expected
    • Led7 is off, is +12V unregulated supply:
      • F116 visual check and does not appear to be blown
      • Nudging related Fuse F116 intermittently activates Led7

Conclusion/Action 1:

  • Conclusion: Power Driver Board Fuse F116 bad joints
  • Action: Resoldered ALL fuse holders on the Power Driver Board

Issue JD-20180324 Left shooter (Missile launch) weak, leaving balls in left shooter lane

Observations:

  • Assembly is part A-16936
  • When playing when ball goes into left shooter lane, shooter appears to be too weak to send ball out

Secondary observations after commencing investigation

  • Solenoid test activates this shooter weakly but also left lower flipper strongly
    • Left Shooter is: Solenoid 04 Brn-Blk/Vio-Orn
    • Left lower flipper is: Flipper 03 Blu-Gry/Gry-Yel

Solution

  • Wiggled the coil connections and problem went away so resoldered coil wires

Update 20190802 Still weak at times

Investigation:

  • Spring is manky / bent, part no is Solenoid Spring 10-135
  • Noticed that the kicker appears almost offline to the ball groove so loosened bracket screens to playfield and realigned slightly

Issue JD-20190802 Top right flipper no return

Observations: Top right flipper appears to be sticking up

Investigation:

  • Doesn’t really look like coil is staying fully on so will assume is mechanical for now
    • Spring is intact
    • EOS switch position looks fine
    • Removed coil:
      • No mushroooming
    • Replaced cool sleeve
    • Shaft end play is minimal but not tight/binding left for now
  •  Checked right flipper coil as well
      • Plunger is mushroomed – ground down for now
      • Replaced coil sleeve
      • Flipper shaft end play was set very loose – made adjustments

Todo (non playfield)

  • Power Driver Board: Resolder/repair fuse holders for GI circuit (Resoldered during Issue JD-20180320)
  • Power Driver Board: Replace all BRs & associated large caps (5V done during Issue JD-20160312)
  • Power Driver Board: J120 is a bit munted, needs replacing one day, has trace jumpers on the underside as well so trace damage

Todo (playfield)  interim to full strip

  • Replace left flipper coil  (FL-11629 Blue 50V)
  • Replace top left flipper coil  (FL-11629 Blue 50V)
  • Remove enough to get to remaining Incandecesents that are under the playfield
  • clean what can be cleaned during the above
  • replace captive balls with something interesting
  • Its a dark machine, needs much light added
