  • Elevator/Turntable Motor Won't Shut Off

    Greetings, everyone. I've had an issue on a Z-4 pinsetter that has been plaguing me for quite some time. A previous head mechanic of mine had an elevator motor go out about 2-3 years ago and replaced it with a spare. The motor will not shut off when the pinsetter shuts off, the only time it will is when the switch over the turntable is turned off, the breaker is disengaged, or the elevator is full up top. Also, the sweep will run when the reset button is pressed, even when the machine is off. Does anyone know how to resolve these weird issues I've got? I'm hoping to get this dealt with after the holidays, but I'd like to have an idea of where to start.

    Do you have relays you can unplug one at a time or a circuit board like a Bowl Mor with a Renner box? I'm guessing if it was relays you would have already found the problem so can you swap the circuit board with another pinsetter? Can you upload some pictures of the electrical box?

      This is my box layout. I have no schematics, manuals, or anything to really go on unfortunately. If you need more
      photos, I’ll take some more.

        Since the turntable and elevator motor will shut off when the pinlift is full I suspect the relay controlling it is okay. You have two circuit boards in the second pic. I suggest that you swap them one at a time with another lane and see if the problem moves. If that doesn't do it you will need to trace the circuits marked pinlift and sweep through each component and compare with another lane.

          Thank you for the reply. I will try that out once I have the ability to.
