Quoted from plovis:

Hey folks, I'm having an issue with the ABC rollovers at the top of the playfield. Typically once one of the ABC lights has been lit, you can move the lit letter around by using the flipper buttons. For some reason, only the left flipper button is moving the letters. Both flippers work fine, so its likely another loose connection somewhere between the right flipper button and the ABC lights, I'm assuming? Just wondering if anyone has encountered anything like this before I start digging around.
