I have a (conversion kitted out) High Speed that’s flipping before you even coin up. A locked on pop melted and caused a few transistors to blow adjacent to K1 (pictured). You can clearly see the damaged transistors. Could this be causing the high power to lock on? I thought this relay was used to switch solenoids between flashers/coils in most System 11s, but not HS... Connector J3 got burnt too. This is on location so I’m a little unsure about the sequence of events. Funny thing is, game played fine just short a pop and some flashers.

Right right. It’s odd, Slings, pops fire along when triggered just like the flippers when out of the game... just like you started a game.

I will check out Q67. I have the board outta the machine now so can’t test the relay, I shoulda done that dang.
