    Can somebody give an explaniton how pins 2, 3, 6 are supposed to be connected. I had a shortcircuit there for the drive motor connection because of water leakage.

    Not quite sure what your asking here. You have the board there. The picture is a little washed out by the light so is there something that has you concerned that I may be missing?

    Below is the wiring diagram for the drive motor for the Model B. This is for the 120V version but the 240V version appears to be the same. Your board appears to have traces to pins 4 and 5 which show no connection on the wiring diagram but looking at the motor plug should show if anything should go to these pins. They may just be for future use.

    Just speculating here but this is an AC motor and 4 wires so it appears you have two wires for the run winding and two wires for the start winding. When the machine reaches the end of the lane the motor needs to reverse so the current through the start winding is reversed and the motor runs in the opposite direction.

    Can you post pictures of the full board both sides. Also can you say with a little more detail what your concerns are and what you are looking to do?

      That is the JP8 drive motor plug inside the control box. Some of the circuit boards soldering area is burnt under this connection part. The problem is of course, even if somebody has this board as a spare it is not so easy to see the connection under the 6-pin connector. AMF is not offering any shematics for boards inside the control box.

        If someone has this board as scrap, I would be wery happy to see a picture of the connection under a removed JP8 connector.
