Hi everyone

I am working on a Gottlieb Volley and am stuck with my troubleshooting on this one. None of the playfield switches are activating any of the score reels. The game starts without issue, kicks the ball into the shooter lane, advances through the balls and goes into game over mode without issue. Playfield lights are on. Everything seems OK except for the fact that nothing will activate the score reels.

When I manually activate the L, M, N relays, the score reel advances and the chimes go off. However, the relays do not do anything when a playfield switch is hit. Pressing the 500 and 5000 relays in the cabinet will advance the score motor, but the score reels will not advance. It's not stuck in tilt. The Jones plugs between the playfield and backbox are securely connected and I have cleaned the contacts on them. No blown fuses anywhere. No playfield switches are stuck closed.

It's like there is a total disconnect between the playfield and score reels but I cannot find where that break is.

Any ideas?

Yes, I'm sure they are all connected. There are 3 in total.

Some further thoughts.

The 10, 100 and 1000 point relays work fine when activated manually. So the issue must be downstream of there. According to the schematic, each relay passes through a switch at 4A. The target bank reset relay also passes through 4A and works fine, so 4A cannot be the issue.

The manual states that scoring is through 1A. I inspected both switches at 1A and cleaned the contacts. They activate properly so they can't be the issue either.

The hunt continues...

Yes

I'll try that tonight

OK, bear with me here as I am new at EM troubleshooting. As I understand it, I need to jumper the black wire on the 10 point relay to the MAR-YEL wire attached to the V relay, then to the RED+WH wire attached to the switch at 1C on the score motor. Is that right?

I checked the AX and V relays and both of them were well adjusted. So then I had a look at motor switch 1C. It was making good contact physically, but when I tested it with my meter, there was no continuity. I gave it a light sand with flexstone and then I got good continuity across the contacts. That turned out to be the problem and now the game scores!

Thanks to everyone who offered advice. This was a good exercise in reading schematics for me so even though it was a simple issue, I spent a lot of time trying to understand the circuit.

One last question: when looking at the V relay, what is the easiest way to tell which switch on the relay is part of this circuit? Is the wire colour the only clue?
