Williams Toledo Electro Mech Pinball 2 player - Problem

[Ronmar]

I have a Williams Toledo Pinball which works great in the 1 player mode. However there is a problem in the 2 player mode and I hope that some one can give me an idea where to go from here. I have the owner's manual and the schematic. I am ex electronics tech so I can get around it but this is driving me crazy.

Problem:
In 1 player play, 3 ball & 5 ball, the games works great.
In 2 player 3 ball, Player 1 & player 2 , ball 1 scoring goes to player 1. ball 2 & 3 score to each player properly.
In 2 player 5 ball, Player 1 & Playr 2 , ball 1 & 2 scoring go to player 1 and ball 3,4,5 score to each player properly.

where do I go from here? Everything is tight and seems to working normal apart from this.

Thanks

Ron

 Start by cleaning the player unit.  Make sure it will 'ratchet' cleanly.

 Some very light instrument oil is needed to lube the unit and the
contacts.
