Hi All,

So this is my first SS machine I've had it for a week and fixed a few issues but i'm mostly used to EM's

The Problem:
Machine works and is playable. When playing the game, the left flipper works but sometimes will also do a Yagov kill.
When some balls are locked, one or two will randomly launch without having achieved the 4 ball lock (but works when all 4 are locked and launches whatever balls are left locked).
On the very random occasion the machine will tilt when the ball is in the upper playfield. Has happened 3 times in about 40 games and I don't bump the machine.

Troubleshooting done:
I've gone into the switch diagnostic and pressing multiple times the flipper only shows the flipper and EOS switched being enabled.
Shaking/banging the machine does nothing (maybe didn't bang hard enough)

I've watched videos on understanding the switch matrix but unsure where to go from there.

I checked and nothing seems to be broken or touching or even close for that matter. I banged and shook the machine really hard this time and it wasn't doing anything. But I have noticed that the Yagov coil fires sometimes when it actually does a "kill" and will also randomly gives 10 points when using the left flipper (but not related to the yagov kill)

I managed to get to the coil, everything is solid and soldered correctly

So I tried that, wiggled every part and wire, got electrocuted a bit in the process when touching a flipper coil haha, but nothing was registering in the switches. As for the common wire, they're all different colors between both lower, upper and yag coil...

Do I assume there's a diode somewhere that it just bad?
