Bally Skill Parade: More broken switch shenanigans

Bally 1958 Skill Parade

So it's Saturday morning, I think to myself: It would be fun to play a few games on Skill Parade...

Drop a Nickel at the top... Flick through the first tier of switches... geta a hippo.
Flick through the second tier. Coin rolls over the Jumbo. Doesn't register. That's odd... maybe the switch is dirty.
Flick through the 3rd tier... get the monkey

Second Switch tier. The red tier


No big loss for that non registering Jumbo the elephant. It wasn't a winning combination anyway.

Play a few more coins, again, at the second tier, hit Jumbo. No trip. No reaction. Nada

That's plain annoying.

Maybe playing games on a lazy Saturday morning isn't a good idea. It's becoming a recurring theme...

I open up the back of the game. Use a jumper on the rollover switch... No trip. The switch isn't the problem. I have a look at the Jumbo-2 switch stack on the trip bank. The problem becomes obvious.

Can you spot the broken blade?

Look for the broken blade

Here's the stack from a different angle


Even worse. I can't seem to find the broken switch blade. It could be anywhere inside, possibly even causing a short circuit. Grrr. Eventually I did find it under the up kicker mechanism.

I took the time to measure the thickness of the broken blade: 0.01 inch. Pretty sure it should have been a 0.008 inch blade. It's way more flexible. And that's what I reinstalled anyway.





Fortunately, I have a donor Bally 2 in 1 pinball machine with a massive trip bank that has plenty of donor switch parts.

That's EM repair life
