My start up sequence stops after reels reset on player one... the score motor (sm) just spins.

I can manually step the player unit (pu) one time and the machine resets.

In trouble shooting I again went thru the AX and now the ball count won't step and it will not go to player 2

without manually stepping it.

Messing with the AX didmt fix the issue it only compounded it!

If someone could send me a pic of their AX I can look to see if mine are misadjusted.

Stepper works thru sm switch A1 and 4c and since those switches are working to

reset player one they should work for player 2

any suggestion or schematic needs I have them.

As always thanx in advance

Each score reel in a 2 player Gottlieb has a switch that is closed at zero. All these switches are connected in series. When all player 1 reels reach zero, the player unit steps once to start resetting player 2 reels. Check the closed at zero switches on your player 1 reels.

Quoted from DirtinLa:

switches look closed and i put my dvom on them they're open

For a switch to work 3 things are necessary:
1) When open, there should be a small space between the contact points (duh)
2) When closing, the long blade's contact point should push the short blade's contact point enough to move the short blade
3) The contact points should be clean, which they usually will be if #2 is happening
