Myford mystro problems

[RonnieI]

Hi, I've had a myford mystro mk2 for about 6 months and today it just stopped. Pressing the green start button I can hear a relay clunk, the red button and it clunks again but no motion. Is this a dud motor or something else electronic? Any ideas?

Swap out the start/stop button - sounds like it isn’t engaging properly

Think it is because the solenoid contactor is pulling in and dropping out when the red button is pressed. Now I've had chance to do a bit more testing, I've only got 13V between each phase and earth so I think it must be the VFD.
