When I run a self test 5 on my 1978 Bally KISS Pinball it is indicating that 18 - Upper 'S' Target is stuck. It is open (see photo) and I tested other switch assembly numbers by closing and opening and they seem to clear. I was going to replace with a new Target Assembly (Red) ASE-2911-3 but I am not sure this will fix the problem.

Any advise would be appreciated.

That worked, it cleared 18 and 0 is showing. So I just have to replace the capacitor?

Thanks so much... Yes, that's that part... Capacitor - 0.047uF 50vdc Ceramic Disc.

Thanks again for your help!
