When the game starts, the score resets to 0, the thermometer resets, one game subtracts, the ball count resets, drop targets reset but the game over light stays on and the ball does eject not to the plunger. I've reviewed every post I could find and checked everything I could check based on those posts. Everything seems to be in order but I'm obviously missing something. The one thing I'm not sure of is what is meant by the "ball roll tilt switch" which was mentioned in a previous post. For what it's worth, everything except the second coin settings had been working great. I tweaked something (I believe it was on the Start Relay) that fixed that problem but now I can't get past Game Over. Any insights would be appreciated.

Thanks in advance.

Thanks for the quick reply. Found the ball roll tilt. Thanks. That is open and does tilt the machine when engaged. My Q relay is labeled as the 500 Point And Add Advance Relay. One thing I forgot to mention is that the Hold Relay does not stay energized once the Start Relay releases. If I press on the Hold Relay to keep it engaged I can the the game started but as soon as you let go of the Hold Relay the Game Over comes back on. And yes, sorry. I did mean that the ball is not set up to the plunger.

I do have the schematic. The Hold relay energizes with the Start relay and stays on until the Start process is completed. One set of contacts on the HR is supposed to energize itself and the are Anti-cheat switches are in line with it. They seem to be working correctly. The HR doesn't look toastier than the others, but I know what you mean. It does hold during the Startup. Can you tell me what voltage holds the relay closed? Just occurred to me that if it's low at the HR contacts, it may point me toward the problem. Not sure if the schematic calls out that voltage, but I can verify that tonight. I'll also see if I can find the Game Over relay but I believe it's handled by the Ball Count relay and the Hold Relay. I will confirm tonight.

Thanks again.

Back in business! Once I knew what the "ball roll tilt switch" was, it was easy to see that the schematic showed that it needed to be closed for the HR to stay energized. It was not. So I jumped it closed to test and everything started working again. Not sure how it ever worked for me, since the "ball" part of the switch was never in place, but it's working now.

Thanks for your help. It's a great feeling to go from Game Over to ringing bells.

Weird, indeed. I spent some time looking at it last night. Not sure how this works on other machines, but the tilt ball closes the the switch which closes that part of the HR circuit AND it enables the tilt plumb rod. It's all very interesting. I can post that segment of the schematic if you'd like to see it.
