| Help! Couple questions with standup machine, PCB and rear panel pressure switch |

;D I'm not unfamiliar with electronics, I have a multimeter, have not had chance to check voltages yet. The PCB sitting on bottom of the cabinet, happened to be how the previous owner had it (that pic was when I went to see it). My goal was a setup with Openjamma board in each machine, so the current PCB is not much of a loss if I can't get it working. Just not sure if it was something simple or not to troubleshoot. Concentration on the switch is due to my habit of being quite particular on things being 99% functional in their original configuration/condition. Take for example one thing I've come across, which is a test switch for the coin system, which someone has removed the wiring from. Just something I will probably wire up again to put back to how it was originally. ;) Sorry, just a stickler that way. Just a bonus if the POW PCB can be made to work, just not high on the list, as there's much more too the restoration I'd like to finish up. I'll check the voltages soon and report back. Been working at stripping the paint off the cabinet to expose the Ms. Pacman graphics luckily still intact. Tim |

Just a quick update, I'm guessing wires not right on the pressure switch, it allows power when in neutral, but shuts off power when pressed in and going to assume when pulled out as well. Just want to figure out at some point how it should be wired up. Tim |

The interlock switch has 2 poles to it. 1 pole has com, NC and NO and the other has the same. If the switch is truly backwards than just swap the wires. If the wires are currently on NO, move them to NC. Leave the commons where they are |

I can't figure out what to swap around. Gonna drive me insane until I figure out how it should be wired. :o So I test voltage on it in different positions. Top blue wire, which comes from the AC outlet plug cord itself, always has power. If switch is pressed in or pulled out, the other three wires never have power. If main power switch is on (unit is powered up) and interlock is in neutral (which is position unit powers up with), both blue wires have power. Two brown never do. Top of two brown goes to main power switch. Other brown goes down to a fuse near transformers. Other blue one goes to what appears to be a filter, next to the transformers. |

Unplug the machine and set your meter to ohms. Using your photo above, number the terminals 1 thru 6, top to bottom. Based on your earlier post, right now you have blue wires on 1 and 2 and when the interlock switch is in the middle position, you should have continuity (<2 ohms) between 1 and 2, but not between 1 and 3 or 2 and 3. Pull the interlock switch out and check for continuity. If 1 and 3 have continuity, then 2 is NC -- attach wires to 1 (COM) and 3(NO). If 2 and 3 have continuity, then 1 is NC -- attach wires to 2 (COM) and 3(NO). Verify that you get the same results when the switch is fully depressed as when it is fully extended. (continuity between NO and COM) Repeat this process for the brown wires on 4-6 -- 4 should be NO. Scott |
