On the Strato flite machine, check if the ball count unit and player up units are completely reset and are opening the zero position switch on each unit. If both of these switches aren’t open, the game over relay trip coil will fire keeping the machine in game over.

On the Cue-T problem. on replay button start up the number of ball count unit advance coil pulses is determined by how long the coin relay can stay pulled in, impulse cam fires 5 pulses, and score motor cam 5 switch A normally closed switch opens to release the coin relay hold circuit. If switch 5A doesn’t have a clean positive connection, the coin relay hold circuit could release at any time or during score motor vibration before the cams get to cam 5 and opens the coin relay hold circuit normally.
