    Flash Right Ramp Bottom (resized).jpg
    #1 5 years ago

    Hi,

    I picked up a couple Monopolies (Monopoli?) that need some TLC. Before I tear them down I waned to make sure the electrical is working (so I know if I bork it up later)

    On Game 1, I've solved all the issues except one. The Right Bottom Ramp Flasher isn't working. I've checked that both the Power and the Control lines have continuity from the socket to the board connector (with connector removed). I don't yet know what the proper resistor values are for that circuit, but they are showing some resistance, so they may or may not be good. The diode also appears to be working (at least compared to the other diodes in that area).

    If you had to guess would you suspect the transistor or is there some other components that I should check?

    Any help appreciated!

    For reference, here is an image of all the good (green) and the one bad (red low current coil/flasher groups)

    Just a quick update: I pulled the board and tested the transistor and it is shot. So, will be replacing that. Hopefully, that solves my last issue.
