Quoted from Jaffafu:Hey i am a beginner and dont understand drawing you have pictures i can see.
In the bottom of the cabinet you'll see a bunch of relays, hopefully labeled. Find the Game Over and match the make/break sw. by wire color if there is more than one. Move the armature by hand to see how it operates.

Here is your game over relay, it is the only relay with two coils attached. It is located on the mech panel, on the bottom of the machine. You need to check MB switch D. It is most likely not opening when you start a game.

Quoted from currieddog:I bet reset isn't getting completed. Check switch C on the Game Over for cleanliness and solid contact.

I have no problem for C, D and E for they only have 2 switches.
For A and B have 3 switch how could i know the right should be open or closed? same also for the left?
20200319_114927 (resized).jpgThe switches only have two states. When the coil is disengaged, the center blade of the make/break switch will be touching one of the blades. When the coil is engaged (or you manually move it) the center blade will move away from the blade it is touching, opening that switch and close to the opposite blade.

You're welcome.
If pressing that button doesn't open the gate, Inspect and diagnose this circuit with Alligator clip jumper wires
