Got a problem with my JP. Every time I hit the right flipper button , the right flipper goes crazy. Makes a loud noise and moves up and down non stop until I let the flipper button go. Does anyone know what this is and how I can fix it?

Thank You

On JP the EOS switches do need to be clean and making contact for the flippers to work properly. One of only a couple games that DE made with that N/C EOS setup. I would look there first...

Yup... and the right side is also the double switch for the upper flipper. I replaced both of my flipper switches when I did some restore on mine and they are much better now.

There's a service bulletin to fix that problem too:
