Hi Tony,
Good look with finding someone local that can help you. I'm Sure we would all be interested in knowing the the solution to the problem. (And giving any more assistance if required.)

Hi All,

Well, guess what – I think I have it sorted. It was something a couple of you said about swapping the phases over. Not being confident with 3 phase wiring I was a bit loath to start playing around with it. But I thought I would give it a go and – hey presto! it worked. And as a bonus, the motor is running in the right direction and I haven't killed myself.

Thanks to all who have offered advice. I really appreciate it.

Cheers, Tony

Excellent news! I can understand it sorting the contactor problem, but not the single phasing on the motor, unless the coil pull was too weak to properly close the contactor. I must admit I am not familiar with artificial 3 phase systems. I have only used capacitor phase shifting for testing motors where proper 3 phase was not availble. Glad to hear it is fixed!
