looking to rewire a ge motor model # 5kcs203xb85f 1hp 14.4/7.20 amp frame 203 type kcs 220/120 volts code k s# d405275 from 220 volt to 120. Home current has 6 wires from motor 2x red 2x black 1x yellow 1x green. It's an old millinig machine with a squared d reversing switch.
it's forward and reversed step down speed. By control of pulleys

Do they have numbers on them.
Many need to connect 1 &3, and 2&4. This will need 120 volts, and you may have a 5 & 8 for reversing. These 2 also get 120 volts, but are swaped with the reversing switch to change direction.
