Hi RASCAL 123
If. you have a look in my photos ( see left ) you will find a folder called MYFORD REVERSING. This will contain a schematic for the Dewhurst. Please remember though that the connection from the mains to the Dewhurst should be made via a NVR switch. This will ensure that , should you get a power cut , the motor wil not restart when power is restored and ,possibly , when you have your fingers in th works!
