I'm a little new to the pinball world but bought my family a Funhouse over Christmas. It had a few issues that I've fixed so far thanks to this forum. But out of nowhere its started making a noise that sounds like its shorting. I've looked and don't see anything that resembles it on the forum. It's hard to explain so I made a clip of the sound.

And insight or help would be much appreciated.

Thank you all for answering!
Rudy’s voice suffers the same as the music. Drowned out under the clicking. Volume control doesn’t appear to affect the clicking. Clicking sound remains constant regardless of volume.
Another interesting thing is that the clicking is not a constant. It does it for a minute or two, then stops for 30 to 120 seconds, then returns.
I’m traveling for work this week, I’ll try to take a better video when I get home tomorrow. The kids love it, so I’d love to get it back up and running but that clicking sound gets teal old, really fast.

Thank you all. I've finally gotten a much longer video that captures Rudy's voice getting the glitch and the music recovering. It appears that its triggered by a music change. Any help is appreciated.
