-Functional:
+__NOTOC__
--Diagnose fuse blowing problem:
-Likely culprit - bad solenoid on jet bumper (already disassembled - discoloured)
--Replace all rubber bumpers
+==Documents==
+Manual is available as a PDF online and on paper inside the machine.
--Realign flippers
+https://www.ipdb.org/files/1970/Williams_1986_Road_Kings_Manual.pdf
--Descale copper contacts/better current flow = better power from flippers
+==Troubleshooting==
--Optional; replace lights with led equivalent/re wire motherboard to work with leds.
+*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. It could also be one of the fuses.
+*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.
--Resolder top front speaker wires, only internal speaker works - top disconnected
+*Please add more problems and solutions as time goes on!
--Find replacement coin rejector - player 2 quarter slot rejector missing
+==To do==
-Formal:
+===Functional===
--redo exterior paint job, replace decals on side (repaint? vinyl decal?)
---image original artwork
+*Diagnose fuse blowing problem
---sand down to wood
+**Likely culprit: bad solenoid on jet bumper (already disassembled - discoloured)
---prime and seal
+*Replace left flipper solenoid
---reapply artwork
+**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

+*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
