Hello

Big noob here and still learning so please be gental

I have a temperamental issue that results in all switches on a column closing and the game ending since Slam Tilt is one of them.

So when i got the machine and turned it on, it had 2 x switch errors. It wasn't a switch error with the switch being closed, it was that the switches had not been hit in 80 games (i think thats when it reports it)

I had a look at the switch under the PF and the wires had been taken off and where just hanging there.

I soldered them back on, and everything worked perfectly

20 or so games later the machine slam tilts when i hit the 'light kickback'

I go into the switch test and the entire column closes when i press that switch.
I turn the machine off and leave it for a day. Turn it on the next day and its fine.
I then play it for 1 week (maybe just 1 game a day) and no issues. Then in the middle of the game Vs Germany slam tilt....
3 weeks later i turn it back on and it has the issue right away in the switch test. I start a game and the issue goes away.

I am guessing the error is on that switch? Here are some pictures of the wiring
Have a stuffed something up?

Currently when it works every single switch on that column works individually without shorting and activating all switches. Is something being grounded?

I understand it might be hard to diagnose since its temperamental

Bump,
can anyone help with any troubleshooting?

Diodes were still on, was just the wires that were off.
Was your issue temperamental or always happening?

I forgot to mention that I disconnected all the connectors off the boards in the backbox and plugged them in and it didnt make a difference when I had the issue
