Reversible Motor confusion

    I have just been given a very nice South Bend 9" metal lathe and have
    found that the motor is apparently not wired correctly. The motor is
    a GE model 5KC 43MG and is made reversible by a Cutler Hammer switch
    that looks to be in good working condition. I have scanned the
    switch/wiring schematic and the link is
    http://im1.shutterfly.com/procserv/47b4df11b3127cce87cb05b771b40000001610
    .. The big problem is that the colors of the actual T-leads are at
    variance with what is shown in the schematic. The motor is the
    correct model as shown in the wiring schematic. The motor does have 5
    leads, the colors being Black, White, Green, Orange and Red. There is
    continuity between the Orange and White leads (probably the start
    winding) and the Black lead goes to one post of the capacitor. I am
    suspecting that the Green and Red leads are the "run" winding. Can
    anyone give me some assistance so I don't let all the smoke out of the
    motor? The way is was wired, the motor would run in when the switch
    was in the reverse position, but would sit and groan until I gave a
    twirl on the pulley, then it ran either direction that I twirled it.

    What's that Lassie? You say that Phideaux fell down the old
    sci.electronics.basics mine and will die if we don't mount a rescue by

    Ask over in:
    rec.crafts.metalworking.
    They know there motor wiring on old shop equipment.
