Is the ball coming up the trough into the shooter lane? If it is and nothing works still, then your trough switch isn't making. The trough switch has to close to step the ball count unit up to ball one and enable everything on the playfield to work.

I'd check the Q relay. A misadjusted switch there would make the game think that it's in Game Over mode and never turn any of the playfield features or flippers on.

Is a ball getting kicked out of the outhole at all or is that dead, too?

The outhole relay will be activated by the outhole switch making. It will pull in and lock on via a switch on that relay and the score motor runs. There is a normally open score motor switch that will activate the outhole coil and kick the ball up, another normally closed motor switch opens and releases the outhole relay. I own the game but I can't get to my schematic right now. What you want to do is find on the schematic the outhole relay and the outhole coil, and locate, clean and adjust all switches in those two paths.

If everything else is resetting, I don't believe the game thinks it is in game over. Something is causing the outhole relay not to activate. Are you sure the outhole relay coil is good, no broken wires etc?

Try this test. Start a game, and then manually close your trough switch. See if that steps the ball count unit to ball one and gets the playfield live.

same problem, still working on mine

Check the jones plugs going from the bottom board and the playfield to the head. Make sure these are all plugged in correctly.

If that isn't the problem, check the switch stack on the back side of the ball count stepper, in particular the 6th position switch. If this switch isn't closed and making good contact, then the O relay won't get power. It is labeled "6th position ball count unit" on the schematic. The switch contacts may be dirty and/or out of adjustment, or there may be a wire busted off at the solder lug of one of the switch blades.

Sorry, working without a schematic I didn't realize the Q relay wasn't going to be a Game Over relay in this game. My apologies. I wasn't trying to say the game would actually be in Game Over, but one of the switches that makes the game switch between being in Game Over to live might be misadjusted. On the Gottlieb schematic I had handy, all the flippers and playfield switches were connected to the main power line through a switch on the Q relay. Maybe that only holds true on certain models of Gottlieb multiplayer?

Anyway, I'd be looking for a switch that should be providing a path from the transformer to the flippers. The 6th position switch, as TimMe mentioned, might fit the bill. I'd be looking down the right side of the schematic for a switch that should be closed, but in your game actually isn't, even if it looks like it is.
