There's too many unknowns and variables to say if the drive is faulty or not. Best guess is a faulty controller as this is the most common failure. I can understand how you saw this as a good deal, but as a good complete s/h unit sells for around £250, you can maybe see it wasn't such a bargain. Returning it might be your best option.

I applied 3v across throttle and ground via an external psu. Again nothing with cranks still or turning.

Pete, what exactly does 's/h unit' refer to?

Ah OK. Haven't come across any second hand kits. Where have you seen them?

Would have been about £200 all in for the kit so not a huge saving on 250, but still a good deal if it had worked like advertised and much cheaper than new.

Guess I'll be looking for another second hand kit/motor now then.

Well, I did try it on mine. Put in the jumper, lifted the rear wheel, and my motor kicked in when I cranked the pedals. Also seen one video on youtube which confirm this works.

If your seller is close enough, maybe he can prove it runs for you.

Buy another bbs but keep the existing unit for spares?
