I recently purchased a dead SO. I have managed to battle through my ignorance and get the game up and fully functioning (pats self on back).

I do have one intermittent problem. Occasionally, the player one 100,000 score light comes on without being earned. Sometimes it comes on during the “reset” cycle, right before the ball is ejected. Other times it randomly comes on during a game in either one player or two player games.

Per the schematic, the last switch before the light relay is the 10,000 score reel P.T. DU. 9th position switch. If I block that switch, the problem does not happen, and of course the light does not come on even when earned.

I have visually compared the switches on both the Player one and Player two 10,000 score wheels and they are set the same.

Any suggestions?

It’s purely due to vibration. You just need to adjust it accordingly. Common on many games with a 100,000 light.

Thanks, I will play with increasing the gap at the contacts.

The first circuit I would check is the normally open (NO) switch on the 1st-Player 100,000-pt relay. That relay is a latch-trip design and the switch that closes to energize the lamp should have a green-black wire and possibly a yellow wire soldered to the switch tabs.

If that switch is gapped too close, it may be resulting in the lamp coming on when it shouldn't.
If that does not turn out to be the issue, then may have to determine if the 1st player 100,000-pt relay is latching prematurely.

Thanks for the suggestions. So far I opened the gap on the position 9 as far as I could, while still allowing it to close when it should. So far (fingers crossed) it seams to have done the trick. Time will tell.
