More advice over the years, I few more from memory or circumstances, not necessarily on PinSide, but also at shows and other forums. Try not to wince.
Round 2: "It's probably just a fuse, an easy fix." (attempted sale after identifying the game did not work properly, this is still a very common comment today)
Round 3: "Check the WPC PDB transistor" (even though it was an EM pinball machine, sometimes a little knowledge is dangerous in the wrong hands, this was a "here's your sign" moment)
Round 4: "Just use some teflon lubricant on the flipper assembly." (instead of replacing the coil sleeve, plunger, and coil stop, and actually cleaning their game)
Round 5: "Spray a little degreaser on the the bolt, and give it a couple of minutes, it will loosen right up." (while the game power was on, you had to see the look on my face, as the owner was completely serious, I asked if he had a fire extinguisher close by)
Round 6: "That is completely normal for game operation, do not worry about it" (massive sparks were flying off of an flipper EOS switch that had partially shorted, like a mini fireworks display, not momentary due to carbon and corrosion pitting of contacts)
Round 7: "I just remove the grounding strap, it resolves the issue." (so I can get electrocuted, but there is more to this story as it was related to grounding issues on a GTB SS80, which the owner did not know how to fix, the owner did mention he had frequent "tickles" while playing)
Round 8: "Spin the leg in a circle, that will get the acorn bolt out." (tearing up the cabinet, Instead of loosening the leg plate, I got the game up on dolley and headed this one off)
Round 9: "Alligator clips are perfectly acceptable for long term electronic repairs and connections, if you worried about them getting loose, hit them with a little daub of solder." (Owner simply being completely lazy)
Round 10: "There is nothing dangerous about a pinball once you turn the power off." (The person then proceeded to burn his face and eyebrows as a large capacitor blew up from a shorted discharge and fat fingers with a screwdriver that slipped)
Bonus: "If you are out of fuses, you can use a rolled piece of tin foil for testing purposes." (Because the person ran out of fuses, from making the same mistake over and over again as the game was never tested for short circuits, ultimately the board had already had further damage upstream from prior attempts at repair with this method)
The list goes on and on.
“The problem with forums is there is a lot of disinformation, and a lot of uninformed opinions affecting what people actually believe. It is normal for forums. In any kind of hobby, go to their forums and blogs, and you will see something very similar. It is the nature of those environments, and it does not even have to be related to pinball machines.”
