Reply To: crompton motor and dewhurst switch problems

[mike smith 5Participant @mikesmith5]

I've got the wiring diagram for the Dewhurst switch to the Crompton motor , I have followed the diagram and this is how it is wired.This is where the problems start ; in forward the motor runs rough and not up to speed,in reverse it trips the power.I had the motor off a friend, he had never bothered with reverse and it was wired up diect to a NVR switch and runs sweet in forward and up to speed. That was connected to AZ and A

I think the problem is that the wires in the motor connection block have been moved about because there are no jumpers to make it run direct from a plug, here is a photo of the motor connection block

wires coming out of the motor housing to the connection block are as follows; 2 red to AZ

red and black to T

black to A

black to Z

capacitor to A and Z

hope you can help as i'm pulling my hair out

many thanks, mike
