Why Wont My Myford Ml7 Start With Same Wiring As Before The Move?

[John Hasler]

Since it´s just been installed I´m quite sure the voltage is 120-140V at each lead.

Odd. I had understood that Sweden used the European standard of 400V phase to phase, 230 phase to neutral.

That looks right. If the motor runs backwards swap any two of the motor wires.

Updated the order of the wire connections, and added the earth wire. Think I got it wright this time.... :-/

I took the liberty to "mark up" the photo of the switch wiring diagram originally given. This further illustrates the 'functional' operation of the switch... I think, anyway.

Cheers!
