    here are two schematic drawings of a single phase dual voltage ,capacitor start motor with centrifugal switch . both drawing's are the same motor ( though id give you two versions of it )your motor is a variation of this motor. This should help you in identifying the motor windings ,so that you can arrange them how ever you need to . I would suggest that you use analog or digital meter ( Simpson 260 //or a fluke multi meter or similar ) both main motor winding sets 1 &2 ,3 &4 should ohm the same resistance ,the start winding will ohm significantly higher than the run winding . note or tag leads after ohming ( I think you'll find the existing color code ( see previous pic ) to be NEMA standards . img_e4319.jpgimg_e4317.jpg

    2. on the front of the board, move the white wire with the ring terminal to T4.
    3. on the front of the board, move the red wire to T5.
    4. on the front of the board, ensure the line-in wires from the switch are on T1 and T3.

    Everything else should be as my earlier drawing.

    Oh, and i'd put a couple big permanent marker 'X' marks over the motor wiring diagrams

    Eureka ! ! That worked
    Thank you very much, Allan, you certainly know what you are talking about
    Thanks again,
    Ted

    LOL! May I rcommend, then... purchase of a vintage top of the line "Monroematic" motor-driven electromechanical "desk" calculator?

    Needs a fair stout "desk" under it, but should keep you out of pubs and brothels for easily a full week, if not a whole month!

    BTDTGTTS!

    I installed the motor and all the wiring on the machine today. Smooth and quiet
    ...but, as luck would have it, forward/reverse is backwards
    I assume I need to switch the red and black wires at the motor...? Since we modified the wiring, I don’t want to assume
    Thanks for your help,
    Ted
