I just acquired a Williams double play and the bat motor keeps running even when game is over. It works, bats, pitches, catches, the turrets all work, it resets correctly and scores properly but the bat motor never stops spinning. Do you know what it could be? I cannot find schematics. Does anyone have them?
Our progress so far......

For example, if I cut the power to the motor by opening a contact, it goes down when stopped. Once power is applied, I goes up.
Upon turning on the machine, the motor starts spinning even before starting a new game. It's as if a contact somewhere is stuck on/closed that applies power constantly.
It does stop for a fraction of a second when the ball is pitched, though. Then, it continues to be constantly on.
Yes, checked and cleaned all contacts. What I noticed is that when the armature is all the way up it is engaged and turns the gears. But, when it is down it still turns the gears. The armature goes up and down in a cycle as it is forever spinning. Are the gears supposed to disengage in the downward position when the playfield is in horizontal (play) mode? Mine moves the top plate that triggers the contacts regardless if it is in the down or up position.
How would I know the model number of the machine. There are different versions of this game and I wanted to find you which I had. The versions are Williams #302 (3/25/65), #326 (engineering update 8/16/65), #327 (novelty), 4/65. Where would I find this information on mine to see which version I have. I understand there is a "relay" that is part of one version but I don't know where it would be located, or which version number I have. Is it stamped somewhere in the cabinet?
Looks like its going to be the motor and/or armature that is worn out. In order to stop the motor from constant spinning is to remove the center brass grommet and manually stop it by tapping the armature and then it stops. You can then play the next pitch, bat, and score or out and repeat the process of manually stopping the motor by tapping the shaft where the fan normally is installed. I had to remove the fan or else it would not be possible. Sometimes when its cold it will work by itself for a game or two and then it will have to be reset manually. Anybody have any these parts or know where I could find them?
