Troubleshooting

• If pressing start button results in soft sound repeated three times "dugga dugga dugga" the machine can not find both balls. One may be stuck/hiding in the playing area or the limit switches that detect the balls near the launcher may be dirty or damaged.
• Powers on but won't feed balls? Check fuses in top cabinet. Front 'glass' lifts up and out, panel swings to the left exposing electrics.
• Sound volume control pot/knob is on the inside, left wall, about 12" in from the front door.
• TILT: The tilt switch is a metal rod hanging inside a round hole in a piece of sheetmetal on the left side wall just inside the door. It may be jammed to one side by the manuals or other contents of the machine.

• Please add more problems and solutions as time goes on!

To do

Functional

• Diagnose fuse blowing problem
  • Likely culprit: bad solenoid on jet bumper (already disassembled - discoloured)
• Replace left flipper solenoid
  • This is the cause of the left flipper sticking on the down-stroke, and the repeated blowing of at least one fuse.
  • Order new solenoid
• Replace all rubber bumpers
  • Order new bumpers
• Realign flippers
  • They keep getting out of alignment no matter how much they are tightened. Maybe threadlocker would help?
• Descale copper contacts
  • Better current flow = better power from flippers
  • Ian did one in Feb 2016.
  • Consider replacing with a different type of switches
• [Optional] Replace lights with LED equivalents/rewire motherboard to work with LEDs
  • Rutger wants to do this pretty much immediately (as of Feb 2016).
  • Frollard is not so optimistic, because the existing matrix depends on the incandescent bulbs' resistance, making LED replacement complicated and likely not at all power-saving.
• Resolder top front speaker wires
  • Only internal speaker works; top disconnected
• Find replacement coin rejector
  • Player 2 quarter slot rejector missing

Formal

• Redo exterior paint job; replace decals on side
  • Repaint?
  • Vinyl decal?
  • Image original artwork
  • Vectorize artwork
  • Sand down to wood
  • Prime and seal
  • Reapply artwork
