Left flipper engages all row 8 switches. Test mode each switch tests good except when I press the left flipper. When I press that one, it engages not only itself, but all the switches in the same row. Any advice would be greatly appreciated. Thank you for your time.

No. I have original board in. I did buy one but had issues with it so put original back in. Bought one because I thought the original board was giving me issues and fuse clips are all very weak or broken. Replaced all flipper components and all was good.

Thanks guys! Only 7 months in the hobby. Still have a lot of learning to do. Learning to navigate pinside. Found a lot of old posts similar and doing my research. My Batman forever is definitely giving me my challenge. I finally figure out one issue to only run into another. I appreciate your time.
