Quoted from Vintage-Pinball:

the game will play but only on ball1, which shows up my 2nd problem because I can play the ball fine but once drained, it wont advance to ball 2

Does the Add Player Unit (P) relay activate when this happens? P should be activated by the Trough switch (different from the Ball Return switch)

If the Add Player Unit solenoid doesn't fire when the P relay does, Inspect and diagnose this circuit with Alligator clip jumper wires

Quoted from Vintage-Pinball:

if I select only 1 player, ball 1 when drains, goes to ball 1, player 2, right up to player 4

On a 1 player game, the Player unit should advance 4 times on each ball drain. If it doesn't check the part of the circuit at the bottom of my picture in my post #4 that goes through the Coin unit wiper and Player unit switches. Let me know if that isn't clear enough and I'll draw a red circle around the relevant switches.

Quoted from Vintage-Pinball:

player 3, ball 3, when drains isnt going to game over.

As part of the Match circuit, the Coin Unit should step down to 0 at the end of a game. If it doesn't Inspect and diagnose this circuit with Alligator clip jumper wires

If the Game Over (Q) relay doesn't activate when the Coin Unit steps down to 0, Inspect and diagnose this circuit with Alligator clip jumper wires
