Was curious to see if anyone had any ideas about a recent switch install I did on my 1990 Bally Dr. Dude Machine. Before the installation, the issue was that the rollover switch was broken, which caused the mixmaster to continuously run throughout the game right when you pressed the start button. I soldered in a new rollover switch and now the mixmaster does not run at all when the switch is activated. I made sure to use the proper solder and that the wires matched up on the switch the same way they did on the old one. Any idea what's going on? I've attached pictures of the old rollover switch before removing and the new one I installed. Thank you for any feedback!

Thanks for the reply LTG. I had a feeling I did the soldering wrong... So just to clarify what you said, unsolder the white wire and move it closer to the black Diode?

Yes the picture helped very much, I will solder the white wire to the other side of the switch. After seeing DumbAss post I am a little confused though if he is saying what you said wont help...

Thank you so much for the detailed pictures. I understand your saying its "obvious what is wrong", but going from what LTG said it seems I just need to move the white wire to "C" on the switch. From your detailed photos and diagarems I don't really see what your are suggesting I do besides what LTG suggests. Professional help is avaialbe, and is coming out this week, I was really just trying to how far I could get with this machine working on it on my own. Thanks again for the detailed pictures.

Thank you for making it more obvious for me! Sorry noob here, slowly learning.

Thanks LTG !

I followed you instructions correctly and made a new solder setup. When I tested it, the mixmaster makes its sound now when before it wouldn't when I triggered the rollover switch! It was really cool to hear it so somthing is working. The only downside is now when the switch is triggered it makes the sound of the mix master,but the mixmaster does not run/turn on like it used to with the broken switch. Hopefully I did the soldering right, I'm not sure now why the Mixmaster does not run but the switch triggers the sound of the mixmaster. The mixmaster ran continuously non stop when a game was started with the old broken switch, now with the new one it does not run at all, but at least the switch triggers the sound which is good. I'm sure the motor of the mix master did not go out or anything so im sure what is going on.

I really appreciate that thank you!

Definitely going to do this next to troubleshoot the issue, I installed some custom coin reject doors and afterward I think my advanced game menu button got unhooked so it's currently not working, plan on fixing it tonight so I can do a coil test, thank you so much for the reply and helpful info!

I fixed the Advance button, when I run a coil test and get to the "Motor" which is the mix master, it does not run. It's odd because it just ran perfect before I installed the new switch, now only the sound (Which did not work with the old switch) of the mixmaster works when the switch is triggered but not the mix master itself. Any Ideas on what could be going on?
