Still working on this old Gottlieb 300.
I'm pretty sure that the (Q) game over and (U) first ball relays should engage as soon as the power is applied to the game.
They do not.
I checked the fuses and all look good.
I am getting lights in the backbox.
One other thing I noticed is that the Tilt light is lit . (none of the tilt switches are closed).
Give me some hints on what this could be or how I could diagnose this problem
I have the schematic and have some small skills in reading it.
