    Hello everyone i have recently put a bally Xs and Os onto location which i had managed to get working very reliably, but of course 3 days later i get a call saying that both lower flippers are "going crazy" so i went down and theyre definately going crazy! Ive checked all end of strokes and they seem to be fine, the cabinet switches could be better but again seem to be fine. Does anybody have any ideas what the issue could be??

    Check the resistance on the flipper coils

    The x's & o's I'm working on had the upper flipper doing the same thing. Turned out to be a bad coil. The hold side was open.

    Quoted from bflagg:

    The x's & o's I'm working on had the upper flipper doing the same thing. Turned out to be a bad coil. The hold side was open.

    Specifically, the winding with the thinner wire is probably broken near one of the terminals. With the EOS switch open, the resistance across the power winding terminals should be 3 ohms and the resistance across the hold winding should be about 350 ohms.

    If there's not enough slack in the broken wire to strip the end and resolder, you can unwind it one turn, cut off the excess and resolder.

    Is there no chance that the issue could he anything else? I find it a bit strange that both lower flippers started to fail at the same time
