Pinball machines contain potentially lethal voltage. Dangerous voltage may remain for a period even after it is unplugged. Prior to opening a pinball machine, be certain to unplug it, then turn it on to insure that it was actually unplugged. It is recommended that the machine be allowed to sit several minutes to allow any remaining power to dissipate. High voltages can be present on any machine, even unplugged, and it can be lethal.
In order to use a digital logic probe, the pinball machine must be turned on and operating. There could be voltages nearby to run plasma / DMD displays that could run several hundred volts. Repair should be left to properly trained personnel. If you are not qualified, you should not work on a pinball machine. Solvents such as isopropyl alcohol and WD40 are flammable and should be used only in a well ventilated area. Do not operate the pinball machine until the vapor has dissipated. Follow all the warnings on the container. Prior to proceeding, ask your self the following questions:ġ) Am I good with electronics and am I qualified to work around high voltages.Ģ) When I find the problem, can I remove the circuit board, remove the defective part and solder in a new component? It is with some trepidation that we write this section. If the answer to either of these two is not a resounding “YES”, then find someone else to work on your pin.
They may look like something one can tackle, but they are amazingly complicated machines.Īnyone planning on troubleshooting a pinball machine will eventually need a digital logic probe, or wish they had one.
If your version of Pinball Arcade does not work, just send me a private message. If you are planning on doing your own electronics work, buy one now, not when you need one. If you want to start the table with a number of players add PLAYERS2 or PLAYERS3 or PLAYERS4 to the end of the command line. They are inexpensive, but generally no longer available at your local electronics store. We prefer a probe that makes an audible tone, so look for that. Digital logic probe – the one we use is from Radio Shack.Clip leads – they come in handy to make connections.DVM – everyone must have a voltmeter to go with the probe.
