Default Williams Aztec player issue

When playing a game with more than one player, sometimes the game won't switch to player 2 after player 1 ball is drained. Going from player 2 to 3, 3 to 4, and 4 back to player 1 has no problem. Just player 1 to 2.

It typically will happen 3 times (meaning give player 1 another 3 turns) before it finally switches to player 2. When this happens the player unit in the back advance coil sometimes will pull in slightly (pulse but not enough to fire the advance coil) and sometimes does not even pulse at all. The Player Unit is clean and moving freely.

The player unit, ball unit and coin unit steppers have all been cleaned and operate freely.

Check score motor cam2 switch with W-Br wire and contacts on
player Reset Relay with Y-Br wire. Those contacts are in series with Player Unit Step Up coil. It seems your ball counter is always getting pulses. The Player Reset Relay diverts those same pulses to the Player Unit advance coil. That seems like a good place to start.

Correct advice. Score motor cam 2 switch B should be lightly filed along with the player reset relay switches that C_S talked about.

I will check these, what is so strange is that it only happens on player 1.

Maybe that will help track your problem down. The circuits and contacts operating 'player 1' get the most ware&tear. These sorts of problems often result from split second errors in timing of switch openings and closings. So player 1 is most likely to fail as things wear down, break, get weak or sloppy backlash.
