Quoted from spookr:I just read a tutorial on Gottlieb schematics and it said the switch name is for the switches on the same named relay.
Yes. The label on each switch on the schematic tells you what relay or other device the switch is mounted on.
Quoted from spookr:I have checked the O switches on the O relay and also the Q switches on the Q relay and find no problems.
How are you checking switches? A visual inspection is unreliable. Unless you can verify that a switch opens and closes electrically when it should you can't really be sure it's working.
Unless there is an unrelated short in the game there are three circuits that can fire the Q/Game Over relay:
Surf Champ Q relay 2 (resized).jpg
Circuit 1 goes through the Score Motor 4C switch and four other switches. It's unlikely to be the problem since all five switches would need to close at the wrong time for the Q/Game Over relay to fire.
Circuit 2 goes through an Make/Break switch on the R/Hold relay. That switch could be the problem.
Circuit 3 is the one suggested earlier that goes through the lock in switch on the Q/Game Over relay and another switch on the AX relay. If the Q/Game Over relay fires as the AX relay relaxes this one is a likely candidate. I also checked the schematic for Surfer which is the 2 player version of this game. According to that schematic the switch in circuit 3 is on the Q relay, not the O relay. You should order a schematic and verify or trace the relevant wires by their colors.
To determine which of these three circuits is the culprit you could block one switch from each path with a piece of paper. With all three circuits blocked the Q relay should not fire. Then by removing the bits of paper one at a time the faulty circuit should reveal itself. You will need to be able to find one switch from each path in the game using the wire colors from the schematic above.
