    You can work this out – you can follow the brush leads back to the block, you can follow the tacho leads back to the block, leaving you 5 wires. 2 will be the safety TOC, 3 will go to the field as it’s a split field motor.

    Armature c. 5 Ohms
    Tacho usually 200-300Ohms – can vary widely with make of motor
    TOC should be near as spit zero Ohms
    Field maybe 5-10 Ohms.

    Chris.
