Gottlieb, 1975This pioneer plays correctly so far. Except when you play a 1 player game it plays 2 players but goes to game over after player 1 ball 3. If you play a 2 player game by pressing the start button twice the game plays correctly. Strange. lol.. I need a clear path to what is going on here if anyone can charm in. Thank you
When you start a one-player game, what players are lit on the backglass? Is the one-player game lamp on, or is the two-player game lamp on? It might be an issue with the coin unit that is not resetting. Check U relay and S relay to see if the contacts are clean and adjusted properly. Also check the operation of the 1D score motor switch...

When start a 1 player game the 1 player out of the 1 or 2 players is lit. I have checked those relays and they look good.
The 6 volt switches of the coin unit or coin relay are in the correct position. So, there might be an issue with the 25 volt switches on the coin unit or coin relay. Examine the coin unit / coin relay and it's switches. Check to see if the switches are dirty or out of adjustment... Also, look at the score motor and manually turn it to see if all the switches are opening and closing properly. Sometimes the switch stack fingers that ride on the score motor discs can be out of adjustment and it will cause issues with the coin unit...

I don't think my Pioneer has a coin unit?

There's nothing between the chime box and the AX, BX, etc relays. There's the two coin count relay behind the score motor, but that's it.
I was reading off some Spirit of 76 information, so it looks like the two player and four player machines control the player up feature differently. ajfclark , do you have a section of the Pioneer schematic that shows the coin count relay circuit?

I can't find the two coins relay in either the manual or the schematic. It's labelled Y in the machine. It's only used when the 2nd chute adjust is set to 2 coins. I don't think it'll have any impact on the problem OP mentions.
CX would be my first thought.
