Which wire goes where

[DaveL]

Do you have a multimeter that can measure resistance?
You should be able to check between pairs of contacts, hopefully you will find 3 pairs with a similar resistance, the 3 coils of the motor. One of the other contacts could of an earth, which could be connected to the body of the motor.

In which case you really don't want to wire one of the phases to the spindle body... that would be a great way to get a very nasty shock.

OP - Take care.
