Hi
I was measuring them using the ground on bob for black multimeter lead and then using the red from multimeter in turn on the mauve , blue and white always keeping black lead from meter on the gnd on bob
The photo earlyer on in thread shows the harness from the tool changer it is the one in the ribbed black sleeve not the one nearest my hand
the two wires that go to the motor are black and brown.
the relay is a bestat BT-125 391k0 12v coil
It has 8 pins on it two for the 12v coil, and two wires going to motor and one 12v and one 24v on the other two pins have been linked across to each other
